Thematic trimester programme with short courses, seminars and workshops
January 6 to April 4, 2025 at the Institut Henri Poincaré, Paris
REGISTRATION IS FREE BUT MANDATORY
Important: the deadline for financial support request is June 15, 2024
The trimester is part of an ongoing effort to bridge two fields of Mathematics : the representation theory of locally compact groups and the theory of operator algebras. These research domains share origins in harmonic analysis, spectral theory and quantum mechanics but grew in separate directions. Recent progress in representation theory, involving especially non-Riemannian symmetric spaces and spherical varieties, and new tools developed in operator algebras, especially those involving K-theory and the other methods of non-commutative geometry, offer exciting prospects for new work at the interface between the two fields.
Research workshops and mini-courses will be the occasion for researchers at every career stage to get acquainted with recent developments in these areas, exchange ideas and explore new research directions.
Graduate students and post-doctoral researchers whose work connects to one or more of the topics of the trimester are particularly encouraged to participate.
Timeline for the trimester (tentative):
