    Microlocal sheaf theory and symplectic geometry

    By Stéphane Guillermou

    IHES

    ... It has been applied some years ago to the study of symplectic geometry of cotangent bundles in papers of Nadler-Zaslow and Tamarkin. I will explain some results of these papers and subsequent works, in particular how we can associate a sheaf with any Hamiltonian isotopy of a cotangent bundle and ...

    A Monge - Ampère Operator in Symplectic Geometry

    By Blaine Lawson

    IHES

    ... This operator makes sense on any symplectic manifold with a Gromov metric, and its solutions are exactly the functions obtained as upper envelopes of Lagrangian plurisubharmonic functions. Both the homogeneous and inhomogeneous Dirichlet problems for this operator are solved on Lagrangian convex ...

    Limits of Symplectic Topology

    By Yakov Eliashberg

    IHES

    ... will discuss several examples illustrating the following general principle: in symplectic topology everything is possible if it is not prohibited by the theory of holomorphic curves.

    Sympletic topology from Poincaré to Gromov

    By Yakov Eliashberg

    IHP

    ... Sur un théorème de géométrie », written shortly before his death,started a development which eventually led to creation of a new field of symplectic topology. In the talk I will highlight some milestones of this process.

    Lefschetz pencils and noncommutative geometry

    By Paul Seidel

    IHES

    This talk concerns the symplectic geometry of Lefschetz pencils. Applying Floer cohomology results in a rich algebraic structure. We will explain a possible framework for understanding this structure, and its relation with mirror symmetry.

    Symplectic Duality and Geometric Langlands Duality

    By Justin Hilburn

    IHES

    It is believed that certain physical dualities of 3d N=4 theory and 4d N=4 gauge theory underlie symplectic duality and geometric Langlandsduality, respectively. By setting up a mathematical model for those physical theories and studying their physical relationship as studied by Gaiotto and Witten ...

The search tool allows you to search through the video titles, abstracts, and other metadata. Various filters are proposed to refine the results. The results can be sorted by date or by relevance (default).

The search tool recognizes the following operators:
  • Quotes ("sample") returning results containing the exact expression;
  • Plus sign (sample+of+search) returning results containing all of the terms separated by +.
