Algebraic analysis and deformation quantization

gesaq — Tue, 16 Jun 2009 09:20:00 +0000

The conference on “Algebraic analysis and Deformation Quantization” will take place in Scalea (Italy) from june 22 to june 29.

Starting conference

gesaq — Wed, 15 Apr 2009 13:31:02 +0000

The starting conference of the GeSAQ project (supported by the french national research agency – ANR) will take place in Montpellier from 4 to 6 may 2009. We will have two external speakers : Ioan Bardulescu and Philippe Roche will explain to us mathematical and physical aspects of the Langlands correspondance.

Kontsevich formality and the Duflo isomorphism

Lecture notes and slides from the workshop on Kontsevich formality, Duflo isomorphism, and Kashiwara-Vergne conjecture, that took place in Warsaw from 6 to 9 april 2009, are available here.

Higher Structures in Mathematics and Physics

From Nov. 3 to Nov. 7 there will be the conference on Higher Structures in Mathematics and Physics in Lausanne.

Journées de Physique Mathématique (in Lyon)

gesaq — Wed, 13 Aug 2008 10:44:53 +0000

From Sept. 3 to Sept. 5 there will be the Journées de Physique Mathématique in Lyon. The program includes three 4 hours lectures: on Deformation Quantization by Martin Bordemann, on Noncommutative Fields Theory by Harald Grosse, and on pertrubative and Constructive Renormalization by Vincent Rivasseau.

GéSAQ

gesaq — Tue, 15 Jul 2008 23:41:13 +0000

This is the Weblog of the project “Géométrie et Stuctures Algébriques Quantiques” (GéSAQ), supported by the french national research agency (ANR).

We will discuss here the news of the project, and maths related to it … that-is-to-say, geometric and algebraic structure arrizing in the quantum world. The leading idea of this project is the parallele between affinization and quantization processes.
