26 January – Thomas Nikolaus: The K-Theory of Z/n

Thomas Nikolaus will indicate how modern tools (such as prismatic cohomology, p-adic Hodge theory, higher algebra) make it possible to tackle fundamental computations, such as K-Theory of finite rings, which have remained open since the 1970s. Thomas Nikolaus is professor of mathematics at the University of

12 January – Diane Maclagan: Tropical geometry

Maclagan will give a gentle introduction to this twenty-first century field, giving some idea of where it can be applied, both inside and outside algebraic geometry. Diane Maclagan is a Professor of Mathematics at the University of Warwick in the United Kingdom.

1 December – Andreas Thom: Equations over groups

The study of equations in the language of groups has a long history and many applications. Thom will explain how topological methods can be applied to solve equations over groups and also mention some recent advances in the study of identities for finite and infinite
