2023-T2 : Higher structures in geometry and mathematical physics

Higher Structures in Geometry and Mathematical Physics

Institut Henri Poincaré, Paris
Amphitheater Darboux
11, rue Pierre et Marie Curie
75005 Paris

Higher structures, in particular homotopy algebras, have appeared in many branches of mathematics and particularly in mathematical physics ranging from deformation theory, derived geometry, enumerative geometry, representation theory, homotopy algebras, Poisson geometry and quantization, mirror symmetry, noncommutative algebraic geometry, string theory and quantum field theory. This IHP trimester aims to promote interaction between mathematicians, physicists and groups working on related areas from different aspects. It brings together leading experts and young researchers in these subjects to address the important questions.
