**Time:** 5:30 - 6:30 p.m ** Place:** Jeffery Hall 118

**Speaker:** Emine Yildirim (Queen's University)

**Title:** Cluster Algebras.

**Abstract:** We will talk about how a fundamental, simple, and old mathematical notion from the 2nd Century called the “Ptolemy relation” reappears in modern mathematics.

Cluster combinatorics is a very interesting, powerful, and one might even say miraculous technical tool studied in many different areas of mathematics, and even discovered in some areas of physics.

For this talk, we will only focus on cluster combinatorics coming from triangulations of polygons.
