Hochschild homology of Fukaya category in mirror symmetry
As Kevin comments, Hochschild homology and cohomology are defined for any $A_\infty$-category $\mathcal{A}$. That includes Fukaya categories of symplectic manifolds and dg enhancements of the bounded …

Has anything precise been written about the Fukaya category and Lagrangian skeletons?
On this topic I've only seen Ganatra's notes from Paul's Talbot talk (see Scott's answer). An aspect of this, that a Fukaya category can behave in a sheafy way, is part of Nadler's proof that "microlo …

How to relate equivariant symplectic cohomology, Contact Homology, Cyclic Homology and Strin...
Some blah on symplectic homology vs. cohomology. There's an invariant $SH(M)$ of Liouville domains $M$ which some people call symplectic homology and some symplectic cohomology. This is the direct lim …

Comparison between Hamiltonian Floer cohomology and Lagrangian Floer cohomology of the diagonal
Michael's answer describes the sort of thing I had in mind when I brusquely dismissed this as "straightforward" in the earlier, big-picture-style answer that Daniel quoted. (Michael, thanks for explai …

Fukaya categories of hyperkahler reductions: general request for information
This sounds like a lovely topic for one or more thesis projects. The relevant definitions are in Seidel's book, as are powerful tools for describing Fukaya categories. The Wehrheim-Woodward functorial …

Are Fukaya categories Calabi-Yau categories?
At first sight, the Fukaya category has obvious cyclic symmetry, because the $A_\infty$ structure maps count points in spaces of rigid pseudo-holomorphic polygons subject to Lagrangian boundary condit …

Generator of a Fukaya category with certain properties
Even without the condition that $HF(L,L)$ is $A_\infty$-isomorphic to $H^\ast(L)$, your conditions are set up in such a way as to disable the standard tricks. This doesn't rule out the existence of ex …

"Fourier-Mukai" functors for Fukaya categories?
I can't speak for these authors, but what I understand by a "Fourier-Mukai" transform between Fukaya categories is the functor between extended Fukaya categories associated with a Lagrangian correspon …

Hochschild (co)homology of Fukaya categories and (quantum) (co)homology
The statement that $HF^{\ast}(X,X)$ is isomorphic to $QH^\ast(X)$ is a version of the Piunikhin-Salamon-Schwarz (PSS) isomorphism (proved, under certain assumptions, in McDuff-Salamon's book "J-holomo …
