The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on January 23, 2024 at 2:00 pm (UTC+2) in Room 478 of IMI.
A talk on:
Complex Dirac structures on flag manifolds
will be delivered by Carlos Augusto Bassani Varea, Universidade Tecnológica Federal do Paraná, Brazil.
Everybody is invited.
Abstract.In this talk we present a description of the invariant complex Dirac structures with constant real index on a maximal flag manifold in terms of the roots of the Lie algebra which defines the flag manifold. As a particular case, when the real index is zero, we have the description of all invariant generalized complex structures on a maximal flag manifold. We also present a classification of the complex Dirac structures under the action of B-transformation. This is a joint work with Cristian Ortiz (IME-USP).
