Miniseries abstract: The Fukaya category is an invariant of a symplectic manifold governing the intersection theory of its Lagrangian submanifolds, built from the pseudoholomorphic disks which bound these Lagrangians. One particularly important version for non-compact symplectic manifolds is the partially wrapped Fukaya category, which plays a prominent role in homological mirror symmetry. This miniseries will lead up to a toolbox for computing and studying structural properties of partially wrapped Fukaya categories. One of the key tools is a descent formula, i.e. a cosheaf property with respect to Weinstein sectorial coverings. We will emphasize concrete examples, and homological mirror symmetry will be a recurring point of reference.

Abstract of talk: This is meant to be a non-technical introduction to Fukaya categories. Fukaya categories are invariants of symplectic manifolds, containing intersection information of Lagrangian submanifolds, and play a vital role in Kontsevich's homological mirror symmetry conjecture. I will also introduce variants of Fukaya categories for exact symplectic manifolds and present some simple examples.
