Organized by Kenji Fukaya, Dusa McDuff, and John Morgan

*January 2 – June 30, 2014*

Gromov-Witten theory, Lagrangian-Floer homology and symplectic field theory arise from the notion of pseudo-holomorphic curves, possibly with boundary conditions, in symplectic manifolds. All these theories rely in a fundamental way on Gromov’s compactness result for moduli spaces of pseudo-holomorphic curves, as well as on results about gluing and transversality. A central issue is how to use these analytic results in various contexts to produce appropriate structures on the moduli spaces, structures that allow one to define a virtual fundamental cycle that can then be used to produce algebraic invariants.

The program will focus on two basic approaches to understanding the structure of these moduli spaces:

(1) local finite-dimensional models derived from the local Kuranishi obstruction picture, and

(2) infinite dimensional analysis — the polyfold approach.

The purpose of this program is to examine foundational analytic and topological questions associated with these approaches, especially in key examples such as the closed case (Gromov-Witten theory), Hamiltonian- and Lagrangian-Floer theory and contact homology. The aim is to compare and contrast the approaches with each other and with alternative methods, such as those in algebraic geometry or those provided by Joyce’s derived smooth manifold theory.
