Abstract
Recently, the Kollar conjecture for weighted homogeneous surface singularity was proved by Jeakwan Jeon and Dongsoo Shin. As a consequence, every irreducible component of the deformation of such singularity is parameterized by the certain partial resolution (P-resolution). In this talk, I will introduce the P-resolution, picture deformation, incidence matrix of a sandwiched surface singularity, and then briefly review the proof.
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.
