Abstract
This talk reviews the work of Alessandro Nobile, From Formal Smoothings to Geometric Smoothing. We would like to recall basic notions of formal schemes, formal deformations and the related smoothing. For a projective, equidimentional singular scheme over an algebraically closed field, the existence of a geometric smoothing implies the existence of a formal smoothing defined by Tziolas. In this talk, we shall address the reverse question giving the sufficient conditions that guarantee the converse.

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.
