On the Fukaya Categories of Higher Genus Surfaces
We construct the Fukaya category of a closed surface equipped with an area
form using only elementary (essentially combinatorial) methods. We also compute
the Grothendieck group of its derived category.Comment: 40 pages, 17 figures. Final Versio
The family Floer functor is faithful
Family Floer theory yields a functor from the Fukaya category of a symplectic
manifold admitting a Lagrangian torus fibration to a (twisted) category of
perfect complexes on the mirror rigid analytic space. This functor is shown to
be faithful by a degeneration argument involving moduli spaces of annuli.Comment: 70 pages, 24 figures. Final version, with substantially enhanced

A geometric criterion for generating the Fukaya category
Given a collection of exact Lagrangians in a Liouville manifold, we construct
a map from the Hochschild homology of the Fukaya category that they generate to
symplectic cohomology. Whenever the identity in symplectic cohomology lies in
the image of this map, we conclude that every Lagrangian lies in the idempotent
closure of the chosen collection. The main new ingredients are (1) the
construction of operations controlled by discs with two outputs on the Fukaya
category, and (2) the Cardy relation.Comment: 42 pages, 4 figures. Minor changes. Final version to appear in Publ.

A cotangent fibre generates the Fukaya category
We prove that the algebra of chains on the based loop space recovers the
derived (wrapped) Fukaya category of the cotangent bundle of a closed smooth
orientable manifold. The main new idea is the proof that a cotangent fibre
generates the Fukaya category using a version of the map from symplectic
cohomology to the homology of the free loop space introduced by Cieliebak and
Latschev.Comment: 40 pages, 10 figures. Minor changes. Final version to appear in
