Cours associés (6)

We study topological groups. Particular attention is devoted to compact and locally compact groups.

This course is an introduction to the theory of Riemann surfaces. Riemann surfaces naturally appear is mathematics in many different ways: as a result of analytic continuation, as quotients of complex

MATH-225: Topology II - fundamental groups

On étudie des notions de topologie générale: unions et quotients d'espaces topologiques; on approfondit les notions de revêtements et de groupe fondamental,et d'attachements de cellules et on démontre

MATH-337: Number theory I.c - Combinatorial number theory

This is an introductory course to combinatorial number theory. The main objective of this course is to learn how to use combinatorial, topological, and analytic methods to solve problems in number the

MATH-662: Perfectoid spaces

The course is about defining perfectoid spaces, and possibly presenting some applications.

MATH-315: Spaces of non-positive curvature and groups

Non-positive curvature is a fundamental aspect of geometry appearing in Euclidean spaces, hyperbolic spaces, trees, buildings and many more spaces. We study it with the general but powerful tool of CA
