Program

The Thematic semester aims to organize a conference, a thematic school, and a lecture series to connect Vietnamese and international mathematicians, and to train participants working in graph theory and related fields. Through invited talks, lectures, and specialized discussions, the activities focus on exchanging recent results and emerging research directions in graph theory, as well as its connections with algorithms and data science; at the same time, they reinforce important knowledge and modern methods of graph theory.

Lecturer: PATRICK MIMPHIS TCHEPMO DJOMEGNI

Abstract

Most real-world problems and the fundamental laws of physics are formulated in terms of differential (often nonlinear) or difference equations (DEs). Despite significant advances in analytical techniques, the majority of nonlinear DEs do not admit explicit solutions. This course is devoted to the analysis of continuous-time dynamical systems, with an emphasis on qualitative rather than quantitative methods. In particular, the module examines system stability and sensitivity to small perturbations.

Born in a letter of Robert Langlands to André Weil in 1967, the Langlands program seeks to establish a far-reaching web of conjectures relating seemingly distant areas of mathematics, primarily number theory, representation theory, and algebraic geometry

This thematic month will focus on some of the most important current directions of this program: the geometric Langlands program, the p-adic Langlands program, the geometrization of the Langlands program, and relative Langlands duality.

General summary: 

Coordinator: Rémi Cocou JAVOHOU (UNSTIM, Benin)

Operator algebras are self-adjoint subalgebras of the bounded operators on a Hilbert space and divide into two main classes: C∗-algebras and von Neumann algebras, according to whether one demands that they are closed in the norm topology or the weak operator topology.
