A gallery model for affine flag varieties »
In this talk, Dr Yusra Naqvi will define positively folded galleries, and then look at a new recursive description of the set of end alcoves of folded galleries which are positive with respect to alcove-induced orientations.

Path signatures in topology, dynamics and data analysis »
In this talk, Professor Nanda will describe the homotopical origins of path signatures, their subsequent application to stochastic analysis, and how they facilitate efficient machine learning in topological data analysis.

The McKay correspondence in higher dimensions »
The McKay correspondence is a surprising, and beautiful, bijection (defined geometrically by du Val, and algebraically by McKay) between the isomorphism classes of Kleinian surfaces singularities and the simply laced Dynkin diagrams.

Using polynomials and complex analysis to check for numerical error in the experimental study of an optimisation algorithm »
Splitting methods are special algorithms that are commonly used to solve optimisation problems for engineering and machine learning.This talk will introduce its main concepts with simple examples, and it features many pictures and the use of dynamical tools for visualisation.

Honeycombs and polytopes: another look at representation theory »
After introducing several geometrical models that can be used to calculate multiplicities in Lie group theory, we describe associated polytopes whose volumes can be considered as approximations of those multiplicities.
