摘要
This talk reviews the work of Bernhard Keller, Hochschild Cohomology and Derived Category. This paper recalls the formation of derived categories and functors and survey invariance results for the Hochschild cohomology of differential graded algebras and categories. We mainly restate the Mather-Yau theorem and apply the theorem to achieve the reconstruction of isolated hypersurface singularity by using the dg singularity category.
