  • The Fukaya category of a log symplectic surface, by C. Kirchhoff-Lukat

    —

    in

    25 Mar 2025, 14:00 CET. Talk by Charlotte Kirchhoff-Lukat. Abstract: Floer theory and Fukaya categories constitute powerful invariants of symplectic manifolds. As a first step in the effort to extend these techniques to Poisson structures with degeneracies, I will present the construction of the Fukaya category for log symplectic Poisson structures on oriented surfaces, with…

  • Projective to Einstein Correspondence, by M. Dunajski

    —

    in

    11 Mar 2025, 15:00 CET (note the unusual time). Talk by Maciej Dunajski. Abstract: I shall review various ways in which an affine connection on a manifold M can be lifted to a conformal structure on TM. I shall focus on the construction in which there is a preferred metric in this conformal structure which…

  • What is the h-principle and how may it be relevant to generalized geometry?, by Á. del Pino

    —

    in ,

    17 Dec 2024. 14:00 CET. Talk by Álvaro del Pino. Abstract: The h-principle is the subfield of Differential Topology dedicated to the classification problem for geometric structures on manifolds, up to homotopy. Statements in h-principle are often of the form: “The space of structures of type X is weakly homotopy equivalent to some other space…

  • Graded geometry and generalized geometry, by R. Mehta

    —

    in

    19 Nov 2024, 14:30 CET (note the time change). Talk by Rajan Mehta. Abstract: I’ll give an overview of graded geometry and explain how various structures that fall under the umbrella of “generalized geometry” (such as Lie algebroids, Poisson manifolds, Jacobi manifolds, Courant algebroids, and generalized complex manifolds) can be viewed as graded geometric objects.…

  • 25 years since the letters to Weinstein, by P. Ševera

    —

    in

    22 Oct 2024, 14:00 CET. Talk by Pavol Ševera. Abstract: I will talk about the original motivations and dreams that lead to these infamous letters (which are known mainly for the introduction and classification of exact Courant algebroids) and about some of the related developments in generalized geometry, higher structures and physics that happened at…
