  • Generalized geometry with skew-symmetric pairing, poster

    —

    in ,

    8 July 2024. Poster by Filip Moučka at the Poisson conference 2024, Napoli. Abstract: Generalized geometry is the study of the geometry of T+T* with the canonical symmetric pairing and the Dorfman bracket. If instead of symmetric pairing one considers the skew-symmetric pairing, the Dorfman bracket is no longer suitable. We introduce a new bracket…

  • Riemannian geometry on Courant algebroids, by F. Moučka

    in ,

    29 Feb 2024, 11h CET. Talk by Filip Moučka. Abstract: We introduce analogues of well known concepts from Riemannian geometry, such as metric, connection, torsion, Levi-Civita connection and curvature in the framework of a general Courant algebroid. We illustrate the usefulness of this theory in theoretical physics by introducing an analogue of the Palatini action…

  • Symmetric Poisson geometry

    26 Jan 2024. Talk by Filip Moučka at the 32nd Winter School on Mathematical Physics, Jánské Lázně, 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…

    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

    —

    in ,

    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.

    in ,

    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…
