 Thursday, September 13, 56 pm in 351 Avery Hall: Building spheres using puzzle pieces

Presentation by professor Alex Zupan.
Topologists like to break up complicated objects into small, manageable pieces. As a simple example, a natural way to split the surface of the earth is to divide it into two pieces, the Northern and Southern Hemispheres. Of course, the earth's surface can also be cut into many more components, and a natural question is to determine how each of these decompositions is related to any other. We consider the problem of cutting up a sphere into topological puzzle pieces in dimension two, three, and four, describing some recent progress (joint with Jeffrey Meier) on a big, unsolved problem in this area.
 Friday, October 19 45 pm in 115 Avery Hall: 12th annual Pi Mu Epsilon Lecture

A New Look at an Old Calculus
Presented by professor Robert Ghrist  Andrea Mitchell professor at the University of Pennsylvania.
Calculus has been around for centuries and has a long tradition of applications spanning the modern history of science. However, the current age is characterized by a sweeping array of new potential applications—to machine learning, AI, robotics, neuroscience, genetics, and much more. In addition, both our curricula and our default modes of instruction (chalk, paper, 4color texts) are not keeping pace with innovation. This talk will be an argument for updating both the content and the mode of visualization of calculus. There will be lots of pictures, new applications, and even a little bit of the mathematics that lies beyond calculus.

 Thursday, October 19 56 pm in 351 Avery Hall: 1distance and almost1distance sets in R^{n}

Presentation by professor David Galvin (Notre Dame U.)
A 1distance set is a set of points any two of which are the same distance apart (so the vertices of an equilateral triangle form a 1distance set in the plane, and the vertices of the regular tetrahedron form one in space). It's well known that the largest 1distance set in ndimensional space has size n+1. While this is a geometric fact, it admits a lovely linear algebra proof.
In 1962 Danzer and Grünbaum asked how large a set can be if it is almost 1distance  pairs of points are close to the same distance apart. They made the reasonable conjecture that the largest almost1distance set is never much larger than the largest 1distance set. Twenty years later, Erdős and Füredi spectacularly disproved this using a probability argument.
Erdős and Füredi's work was highly nonconstructive. Nicely illustrating that one can never predict where a mathematical problem is going to go next, recently Zakharov, a highschool student in Moscow, revisited the linear algebra approach, and improved on Erdős and Füredi's result  this time in a completely constructive way.
I'll talk about some of this work, and mention a few nice open questions.  Tuesday, October 24 56 pm in 119 Avery Hall: Course Preview for Spring 2018

 Wednesday, November 1st 45 pm in 115 Avery Hall: 11th annual Pi Mu Epsilon Lecture Maxwell's Problem, 150 years later: from bridges to nanomechanics

Presented by professor Ileana Streinu (Smith College).
Finding a combinatorial characterization for rigid barandjoint frameworks in dimensions higher than 3 is an easytostate yet elusive, long standing open problem in rigidity theory, originating in two geometry papers from the 19th century of the renowned physicist James Clerk Maxwell. I will summarize our current state of knowledge on Maxwell's problem, and present recent developments leading to a surprising range of applications, from folding robot arms and origami to anayzing the flexibility of molecules and designing materials with unusual mechanical properties.
No advanced prerequisites are necessary. To help build the geometric and kinematic intuitions, the relevant mathematical concepts and techniques will be introduced primarily through physical models and animated graphics.

 Errors, Eavesdroppers, and Enormous Matrices
Abstract. Join us for a tour of the mathematics of information security! Cryptography aims to protect information from malicious eavesdroppers. Coding theory aims to protect information from inadvertent errors  consequences of a noisy environment. These are two very different problems  but amazingly enough, solutions to one problem can be used to build solutions to the other. We'll talk through some fundamental principles and key ideas in both coding theory and cryptography, with an end goal of appreciating their intersection: the future of postquantum security.

 Can mathematicians compute our way out of doing math?
As computers gain a stronger hold in mathematics, should mathematicians start to worry? Computers obviously depend on mathematics, but more and more areas of mathematics are starting to depend on computers. Does this mixture violate the purity of mathematics? Will the beauty of mathematics be forgotten, reduced to cold hard computation? Fortunately, the situation may be not so scary. We will see many examples of mathematics and computers living happily together. Moreover, pairing these disciplines can be beneficial to both sides. I will argue that computers do not spell doom for mathematics; indeed, they make mathematics more exciting than ever.

 Equidecomposability of Polygons
Abstract. There are many ways of comparing polygons. For instance, we could compare their areas or perimeters. We could also ask if they are similar or congruent. In this talk we will explore a notion of comparing polygons, called equidecomposability, that involves breaking them into pieces and comparing the pieces. We'll look at some examples and then sketch a proof showing that equidecomposability is equivalent to having the same area.

Mathematical Ecology: Modeling Fish Harvesting Strategies
Abstract. Overfishing, pollution and other environmental factors have greatly reduced commercially valuable stocks of fish. In a 2006 Science article, a group of ecologists and economists warned that the world may run out of seafood from natural stocks if overfishing continues at current rates. We will use simple models to explore the interaction between constant proportion and periodic proportion harvest policies. We will analyze how they might be applied to the Gulf of Alaska Pacific halibut fishery and the Georges Bank Atlantic cod fishery, based on harvesting data from 1975 to 2007.
This event is sponsored by the Nebraska Math Scholars program, funded by the National Science foundation.

We will use probability theory and computer simulations to explore how populations respond to uncertain environmental conditions. We'll consider a "disturbance specialist" plant, which is a plant that will die off unless a disturbance, such as a burrowing animal, shakes loose the seeds in its seed bank. We will illustrate this with a wild sunflower, a disturbance specialist plant that is native to Nebraska and Kansas.
This talk will be held in the hightech classroom Avery 12, so you can run simulations in R.
If you prefer to use your own computer, feel free to bring it. We'll help you install the program and run the code.You can optionally predownload R for free here.

 Thursday, February 14 at 4:30pm in Avery 108: Talk by Professor Keri Kornelson:

Loosen up! An Introduction to Frames.
Abstract. An orthonormal basis (ONB) in a finitedimensional space like R^{n} has a lot of useful and efficient properties, which is why a great deal of what you learn in linear algebra makes use of ONBs. There are a wide range of applications to other areas of math and science as well where ONBs play a crucial role. But in this talk, we will discuss some of the drawbacks of ONBs. We find that a somehow looser set of vectors (called a frame) might maintain the positive attributes of the ONB while overcoming some of the flaws.

Counting techniques and the game SET
Abstract. SET is a multiperson card game in which the goal is to collect particular sets of three cards from a group of 12 (or more). The person with the most SETs by the end of the game wins. We will use different counting techniques to answer some interesting questions about the game, including: what is the size of the largest group of cards that does not contain a SET?, and, what is the most common type of SET? It turns out, one of the questions above was actually answered 11 years before the game was invented! In this talk we will relate this proof back to the game SET and discuss some generalizations.

Penrose Tilings: "Impossible" Symmetries in Math, Crystals, and Art
Tiling a floor with a few standard tiles has been a practical problem for a long time. It is also a mathematical problem and, in spite of its long history, there have been surprising recent discoveries. There are two tiles, discovered in the 1970's, that tile the whole plane, but only in a nonrepetitive way, something that had been thought to be impossible. We'll talk about what a nonrepetitive tiling is, what we know about them, and a bit about how they appear in both physics (as quasicrystals) and art (as Islamic building decorations of the 13th Century).
And of course there'll be Pizza!  Thursday, September 6, at 5:00 pm in Avery 12: Introduction to typesetting mathematics with LaTeX

Title: How to understand shapes of leaves and flowers through Mathematical Analysis and Geometry
Abstract. In certain circumstances, growing tissues such as leaves, flowers or some small marine invertebrate organism develop curious wavylike patterns, resembling curves and ruffles at the edge of a thorn plastic sheet. It turns out that 'morphogenesis by growth' can be rigorously studied through a mathematical model, in which the distances between points (e.g. cells) are measured in a nonstandard way. In this elementary talk, I will try to explain what Mathematical Analysis, Algebra and Geometry have to do with this business.
Preceded by a Brown Bag Lunch with the speaker in Avery 348, 12:30  2 pm.

Title: A Friendly Discussion of Light, Space, the Universe, and Everything...And Groups!
Abstract. This talk is mostly meant to be a justification for the statement, "REU's and other Undergraduate Research Experiences are awesome." To this effect, I will speak very generally about some of the mathematical ideas that I studied in the REU on Geometry through Lie Groups last summer at the University of Utah. These ideas include group actions, smashing shapes with textbooks, Cayley Graphs, living in nonEuclidean universes, and light in Einstein's universe.  February 913, 2012

 Thursday, April 5 at 5 pm in Avery 106: Talk by graduate student Derrick Stolee

Title: Symmetry, Groups, and Graphs
Abstract. Symmetry is something that everyone understands intuitively, since we see it so frequently in art, nature, and ourselves. We will explore a mathematical version of symmetry called group actions. In particular, we will investigate symmetries of combinatorial objects called graphs. Graphs have many practical purposes, but mostly we find that every type of symmetry imaginable can be encoded into a graph.  Thursday, April 12 at 5 pm in Avery 106: Talk by senior math undergraduate Adam Azzam

Title: Sperner's Lemma and its Continuous Corollaries
Abstract. In this talk I will present a celebrated mathematical result known as Sperner's Lemma. While it originated in the context of combinatorics and graph colorings, it also has surprisingly powerful applications to analysis and topology. In particular, I'll use Sperner's Lemma to prove the Intermediate Value Theorem, the Brouwer and Kakutani Fixed Point Theorems (with applications to nonlinear equations), and establish the existence of Nash Equilibria for nperson games with mixed strategies.

Reflections on a planar landscape.
Abstract. We will make a foray into a beautiful interplay between geometry and computer science. For reflections a, b, and c about three lines the plane, a composition of these three functions (for example abaccbcbabcaba) may end up not moving any of the points in the plane. We'll talk about deciding when this happens, and what sort of computer  if any  can determine the answer.

Join us for some pizza, refreshments, and listen to Adam Azzam speak about his exciting research work at an REU site this summer:
Embroidering in Hilbert Space.
Abstract. If you ask a firstyear calculus student how class is going, they might beg you to "make the derivatives stop!" Underlying this futile request lies a subtle question: how many functions can you "get" by taking the derivative of a given function? Start with a polynomial? The derivative eventually smashes it to zero. Start with sine or cosine? It eventually repeats. Start with an exponential? You can't expect much change. How chaotic can this predictable process of taking derivatives be? Wild. In this talk, I'll present some basic theorems and some new results demonstrating how chaotic these linear functions can be.
 Friday October 14: AMS Conference Poster Session

 Thursday December 8 at 5 pm in 347 Avery: Talk by Dorea VierlingClaassen

My path from Math 221 to Neuroscience
Abstract. Since graduating from the UNL math department as an undergrad in 2001, I have been forging a career at the interface of dynamical systems mathematics and cuttingedge experimental neuroscience.
I did my graduate work at Boston University, using differential equations to study brain rhythms in schizophrenia. Since then, I've been doing research in both experimental and computational neuroscience at MIT and Brown University.
In this talk and discussion I'll take you on a whirlwind tour of the biological topics I've researched, via the gateway of my mathematics education, and talk about the career steps that got me from differential equations class my sophomore year to my current work in electrophysiology and computational neuroscience. I'll be looking forward to your questions about mathematics, neuroscience, and how I've balanced family and career.  Thursday January 20 at 5:00pm in 106 Avery

 Thursday, April 7 at 5:00pm in 106 Avery
 UNL Math Professor Daniel Toundykov will speak on "Efficient multiplication with the Fast Fourier Transform":
Abstract: Fast arithmetic for large numbers, hundreds or thousands of digits in length, has become increasingly important in number theory research, combinatorics problems, cryptography, and arbitraryprecision computing. However, even specialized computer processors are limited to about 19 significant digits per operation, and must be supplemented by software algorithms to handle higherprecision arithmetic. The standard long division and multiplication procedures are too inefficient for this purpose. I will describe the ideas behind the fastest known multiplication algorithms based on the discrete Fourier transform, and discuss connections of integer multiplication with algebra and complex analysis.

"Prime Distance Graphs: Making Difficult Problems Seem Easier Using Pretty Diagrams".
Abstract. A graph is a prime distance graph if its vertices can be labeled with distinct integers such that for any two adjacent vertices, the difference of their labels is prime. Surprisingly, some wellknown theorems and longstanding conjectures in number theory are closely connected to questions about prime distance graphs. In this talk we'll investigate some of these connections and fail to prove any of the longstanding conjectures. No previous knowledge of graph theory or number theory will be assumed.

Chief Undergraduate Advisor Gordon Woodward will discuss summer research opportunities, and
Tyler Lemburg will give a talk entitled
Baseball Cards and Matrices
Suppose a collector wants to collect a complete set of n unique baseball cards, and he can collect p unique cards in a pack at one time, with replacement. What is the probability he will have his complete set after buying t packs? This ``Baseball Card Collector's Problem", also known as the ``Coupon Collector's Problem", has been thoroughly studied for p=1. However, say the collector wants to have c complete sets instead of just 1. To answer the above question in this case, basic inclusion/exclusion combinatorics will not suffice. Instead, transition matrices representing the probability of going between certain states in the problem give us the tools to formulate probabilities for c=2 and p=1. Tools for higher c and p are demonstrated, but the solutions become very complex. This research was carried out at the Clemson University summer REU, which will be highlighted in the talk.
