摘要

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.
