algebraic geometry seminar Tuesday April 16 at 4pm

[Barbara Fantechi]

Dhyan Aranha (Sissa) will talk in Room 136, Tuesday April 16 at 4pm.

Title: The higher intrinsic normal cone.

Abstract: Building on the work of Behrend and Fantechi who constructed
virtual fundamental classes for Deligne-Mumford stacks we construct virtual
classes for Artin stacks. Our methods make heavy use of Lurie's
\infty-mathematics and in some sense the main goal of the talk is to
explain how Lurie's technology offers conceptual clarifications and that
one can in fact deduce concrete results from it. Joint with Piotr
Pstragowski.
