**Title:** Symmetry and [Inverse Semi]Groups

**Abstract:** A group is an important mathematical
object that captures the idea of
symmetry. For example, rotations and
reflections of an equilateral triangle
can be expressed as a group. But what
about the symmetries of something like
the Sierpinski Triangle, which is made
up of three smaller Sierpinski Triangles?
In this talk, I will define what a group is
and give some examples of groups.
Then we will look at how we can tweak
the definition in order to capture these
"partial symmetries".

Welcome to another semester at UNL!

This semester presents some unique challenges, and a strong social network seems more important than ever. The UNL AWM (Association for Women in Mathematics) chapter invites you to kick off the semester with a friendly online gathering. This will be an opportunity for you to meet fellow math majors, learn about what classes you might be taking together this semester, or discuss common interest within or outside of mathematics. We especially encourage students of all under-represented genders to attend.

### About Math Club
