Welcome to this seminar held by Jack Smith with title "Hochschild cohomology of the Fukaya category via Floer cohomology with coefficients".
Abstract: The Hochschild cohomology of the Fukaya category is an important
symplectic invariant, and plays a central role in the generation
criterion of Abouzaid and Sheridan. Unfortunately, it is usually very
difficult to calculate directly. I will describe new results relating
it to a more geometric and computable object, namely Floer cohomology of
a Lagrangian with enriched coefficients, and discuss some applications.
Perhaps surprisingly, matrix factorisations make an important appearance.
