## Cluster structures on Grassmannians: geometry informing algebra

Prof. Dr. Karin Baur talk

**Date:** 20.03.19 **Time:** 15.45 - 18.00 **Room:** ETH HG G 43

Algebra, Geometry and Combinatorics are closely linked. Starting from classical theorems by Pythagoras and Ptolemy we will discuss the combinatorics of triangulations of surfaces and of dimer models on disks. This yields a beautiful approach to cluster algebras. Of particular interest are approaches to Grassmannian Cluster algebras with their impact on representation theory.
