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 
∞-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.
