摘要

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.
