# Degeneration of dynamical difference equations

**Date**: Friday 17 March 2017, 16:00 – 17:00**Location**: Clothworkers North Building LT (Cinema) (2.31)**Type**: Applied Mathematics seminars, Colloquia, Seminar series**Cost**: Free

#### Martina Balagovic, Newcastle University. Part of the integral systems seminar series and algebra, geometry and integrable systems colloquium.

I will describe how, under Drinfeld’s degeneration of quantum loop algebras to Yangians, the trigonometric dynamical difference equations for the quantum affine algebra degenerate to the trigonometric Casimir differential equations for Yangians. I will explain all necessary prerequisites and results needed to state this claim precisely, and sketch the idea of the proof.

Tea/coffee will be available at 3.40pm on level 9 of the School of Mathematics.
