Dear Proponents of Hamiltonian Systems,
The next talk at our seminar by Arkady Vaintrob (University of Oregon) -- Differential graded manifolds and deformations of geometric structures is on Tuesday, October 11, 2022 at 12PM EST (18:00 in Europe, 9:00am
in Arizona, California, and Oregon).
Abstract: A differential-graded (dg) manifold is a manifold equipped with a sheaf of quasi-free differential graded algebras. (They are also known as Q-manifolds or supermanifolds with homological vector fields.) Many geometric and algebraic structures can be described in terms of dg-manifolds. I will start with general results about deformations and normal forms of dg-manifolds and related objects (dg-submanifolds and bundles) and then will show how they can be applied to the study deformations of various "traditional" geometric structures, such as Poisson manifolds, Lie algebroids, bialgebroids, (generalized) complex structures and their combinations (e.g. a complex manifold with a bundle or a Lie algebroid pair).
We'll keep the Zoom coordinates the same:
