    1/3 Classical transversality methods in SFT

    By Chris Wendl

    IHES

    ... inhomogeneous perturbations, and sketch proofs of the standard theorems stating that the moduli space of regular J-holomorphic curves in symplectic cobordisms is a smooth orbifold, and that all somewhere injective curves are regular for generic J.

    3/3 Lagrangian Floer cohomology in families

    By Mohammed Abouzaid

    IHES

    We will begin with a brief overview of Lagrangian Floer cohomology, in a setting designed to minimise technical difficulties (i.e. no bubbling). Then we will ponder the question of what happens to Floer theory when we vary Lagrangians in families, which we will not require to be Hamiltonian. We ...

    1/3 Obstruction Bundle Gluing

    By Michael Hutchings

    IHES

    Obstruction bundle gluing is a method of calculating the number of ways of gluing certain configurations in which transversality fails, but not too badly. We will introduce this technique and show how it works in simple examples from Morse theory, contact homology, and embedded contact homology. ...

    2/3 Obstruction Bundle Gluing

    By Michael Hutchings

    IHES

    There are easy examples showing that classical transversality methods cannot always succeed for multiply covered holomorphic curves, but the situation is not hopeless. In this talk I will describe two approaches that sometimes lead to interesting results: (1) analytic perturbation theory, and ...

    An Integral lift of contact homology

    By Joanna Nelson

    IHES

    Cylindrical contact homology is arguably one of the more notorious Floer-theoretic constructions. The past decade has been less than kind to this theory, as the growing knowledge of gaps in its foundations has tarnished its claim to being a well-defined contact invariant. However, jointly with ...

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 +.
