Description
In the last years there have been renewed interests in vertex algebras in various areas of mathematics and physics. For instance, although vertex algebras have their origin in two-dimensional conformal field theory, many new connections have been found recently between vertex algebras and higher dimensional quantum field theories. The AGT correspondence by Alday, Gaiotto, and Tachikawa, the 4D/2D duality by Beem, Lemos, Liendo, Peelaers, Rastelli, and van Rees, Vertex Algebras at the Corner by Gaiotto and Rapcak, and the vertex algebras VOA[M4] by Feigin and Gukov are examples of such phenomena. It has been also observed that certain vertex algebras called W-algebras play an essential role in the quantum geometric Langlands program. The Mathieu moonshine conjecture and its generalization are giving new insights to the theory of automorphic forms. All these exciting new developments are deeply connected with geometric representation theory.
This conference intends to bring together experts, including physicists, at an
international scale on these new aspects of vertex algebras. This will be an opportunity to encourage young researchers to get involved in these promising developments.
Les algèbres vertex ont connu ces dernières années un regain d’intérêt dans différentes branches des mathématiques et de la physique. Par exemple, bien que les algèbres vertex trouvent leur origine dans la théorie conforme des champs en dimension deux, de nombreux liens entre les algèbres vertex et des théories quantiques des champs en dimensions supérieures furent récemment établis. La correspondance AGT de Alday, Gaiotto et Tachikawa, la dualité 4D/2D de Beem, Lemos, Liendo, Peelaers, Rastelli et van Rees, les algèbres vertex d’angle de Gaiotto et Rapcak, ainsi que les algèbres vertex VOA[M4] de Feigin et Gukov sont des exemples de tels phénomènes. Soulignons de plus que certaines algèbres vertex, appelées W-algèbres, jouent un rôle essentiel dans le programme géométrique quantique de Langlands. Dans une direction un peu différente, la conjecture du Mathieu moonshine et ses généralisations apportent un éclairage nouveau sur la théorie des formes automorphes. Ces avancées spectaculaires sont inhérentes à  la théorie géométrique des représentations.
Cette conférence a pour but de regrouper les meilleurs experts, notamment des
physiciens, autour de ces aspects récents de la théorie des algèbres vertex. Elle sera une occasion d’encourager de jeunes chercheurs à poursuivre leurs travaux autour de ces nouveaux développements très prometteurs.
The meeting is in person and not hybrid
