Math Club Events

Fall 2017

Sunday, August 20 at 6:30pm on Memorial Stadium Loop: BIG RED WELCOME

The Math Club and Pi Mu Epsilon will have a table at the Big Red Welcome event. Stop by to meet some of the Math Club members and learn about the upcoming events, competitions and opportunities for undergraduates in mathematics.

Thursday, August 31st 5-6 pm in 351 Avery Hall: Using Difference Equations and Linear Algebra to Develop Rating Systems for National Football League Teams

Presentation by professor Eric Eager (U. Wisconsin La Crosse)

This talk will discuss various ways to measure the strength of teams in the National Football League. Prof. Eager will compare these rankings, highlighting where and why discrepancies arise, and show how they can be used to predict who will win and/or cover the Vegas spread in various matchups week-to-week during the course of a season.

Tuesday, September 12 5-7 pm in 345 Avery Hall: GRE Prep Workshop

Come study for the Math Subject GRE together with other students taking this exam this year. Graduate students will offer advice on study and exam taking strategies.

Friday, October 6 3-5 pm in 18 Avery Hall: Meet, greet and play games!

The Math Club will be holding a meet and greet event for math majors and other students interested in math in the undergraduate lounge located in Avery Hall room 18. Professors and staff in the Math Department are also invited to stop by so you can meet them and network with them in a relaxed setting. There will be games for all to play as well as light refreshments.

Thursday, October 19 5-6 pm in 351 Avery Hall: 1-distance and almost-1-distance sets in Rn

Presentation by professor David Galvin (Notre Dame U.)

A ​1-distance set is a set of points any two of which are the same distance apart (so the vertices of an equilateral triangle form a 1-distance set in the plane, and the vertices of the regular tetrahedron form one in space). It's well known that the largest 1-distance set in n-dimensional 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 1-distance - pairs of points are close to the same​ distance apart. They made the reasonable conjecture that the largest almost-1-distance set is never much larger than the largest 1​-​distance set. Twenty years later, Erdős and Füredi spectacularly disproved this using a probability argument.

Erdős and Füredi's work was highly non-constructive. Nicely illustrating that one can never predict where a mathematical problem is going to go next, recently Zakharov, a high-school 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 5-6 pm in 119 Avery Hall: Course Preview for Spring 2018

Come find out about upper level math classes for the Spring 2018 semester from the instructors teaching these classes.

Wednesday, November 1st 4-5 pm in 115 Avery Hall: 11th annual Pi Mu Epsilon Lecture Maxwell's Problem, 150 years later: from bridges to nano-mechanics

Presented by professor Ileana Streinu (Smith College).

Finding a combinatorial characterization for rigid bar-and-joint frameworks in dimensions higher than 3 is an easy-to-state 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.

Thursday, November 9 4-5 pm in 351 Avery Hall: CV Workshop

A staff member from UNL's Career Services will offer tips on how to write a great CV for employment or graduate school applications.

Thursday, November 16: UNL Math Day - 28th edition
Friday, December 1st 3:30-4:30 pm in 345 Avery Hall: Undergraduate Creative Acrivities & Research Experiences (UCARE)

Find out about the UCARE program that allows undergraduate students to perform research under the supervision of a faculty member and offers stipends for this research activity. A panel of math majors who are currently participating in the UCARE program will be invited to share their experiences.

Saturday, December 2nd: The William Lowell Putnam Mathematical Competition
