Generalized geometry through Clifford algebra glasses
25 Jan 2024. Talk by Roberto Rubio at the Cable Car Algebra Seminar (Technion-UHaifa), University of Haifa. Abstract: Generalized geometry is a recent approach to geometric structures encompassing symplectic and complex geometry. At its heart lies a Clifford module, which is essentially a global version of the spin representation of the Clifford algebra. In this…

Symmetric Poisson geometry
18 Jan 2024. Talk by Filip Moučka at the 44th Winter School Geometry and Physics, Srni, Czech Republic. Abstract: A Poisson manifold is a generalization of the notion of phase space from Hamiltonian mechanics. It is a manifold endowed with a skew-symmetric bivector field such that the Schouten bracket of the bivector field with itself vanishes.…

Symmetric Cartan calculus, symmetric Poisson geometry, and Cn-generalized geometry
31 Oct 2023. Talk by Filip Moučka at the Geometry Seminar (LIGAT), UAB. Abstract: We introduce analogues of the exterior derivative, the Lie derivative, and the Lie bracket of vector fields, on the algebra of completely symmetric covariant tensor fields. Then we discuss the basic properties and geometrical interpretation of these objects. Using the correspondence…

Cartan calculus on symmetric algebra.
7 Sep 23. Talk by Filip Moučka at the Training School on Cartan Geometry, Brno. Abstract: Cartan calculus on the space of symmetric tensor fields will be introduced. First, we find a certain analogue of the exterior derivative. Then we will define analogues of the Lie derivative and the Lie bracket of vector fields in…
