课程简介：
(1) Basics of dg categories.

We review basic notions of dg categories, such as its definition, dg-modules, perfect modules, generators, and so on.

(2) The dg category of matrix factorizations.

We define and discuss various Hochschild invariants of the dg category of matrix factorizations.

(3) Curved Koszul duality

We discuss the use of Koszul duality in understanding and explicitly computing the dg category of matrix factorizations.

A basic knowledge of linear algebra and homological algebra is sufficient for the short course.
