Abstract
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.
Speaker Intro
Hu chuangqiang joined Bimsa in the autumn of 2021. The main research fields include: coding theory, function field and number theory, singularity theory. In recent years, he has made a series of academic achievements in the research of quantum codes, algebraic geometric codes, Drinfeld modules, elliptic singular points, Yau Lie algebras and other studies. He has published 13 papers in famous academic journals such as IEEE Trans. on IT., Final Fields and their Applications, Designs, Codes and Cryptography. He has been invited to attend domestic and international academic conferences for many times and made conference reports.
