Algebraic structures in the theory of holomorphic curves workshop information The theory of holomorphic curves in symplectic manifolds leads to rich algebraic structures. The study of these structures is increasingly important both for understanding the theory itself, and for actual computations and applications. The aim of the workshop is to survey ongoing developments in the area. Some of the topics of interest are: * cohomological field theories; * relative and tropical Gromov-Witten invariants; * Symplectic Field Theory (SFT) and connections with string topology; * theories of holomorphic curves with Lagrangian boundary conditions, such as relative SFT, open Gromov-Witten theory, and Fukaya categories.
