This week in the Graduate Algebra Group, we have Colin Lawson giving a fun talk about sandpiles!

Where: GAB 473 (Library)

When: Tuesday, January 21 @ 3:45pm.

Title: A Fun Talk: Sandpile Group

Abstract: In this talk we will explore a small case of a sandpile group. I will first explain what sandpiles are and how we may combine them. Then we will look at the subset of these sandpiles that make up the sandpile group. Last, we will briefly look at some symmetry of the identity elements for some other cases of sandpile groups.

This talk is a *very* elementary introduction to the sandpile group.
