Abstract Jarod Alper - Lecture 2

Jarod Alper will speak on  Equivariant Artin algebraization and local structure theorems

After reviewing Artin’s seminar work on approximation and algebraization, we will introduce an equivariant version of his algebraization theorem.  We will combine Equivariant Artin algebraization with deformation theory and Tannaka duality to prove local structure theorems for algebraic stacks.
