#### A Quick Introduction to Diffeologies

###### Seth Wolbert (UIUC Math)

Abstract: The aim of this talk will be to give a quick introduction to the concept of a diffeology. These generalizations of finite dimensional smooth manifolds allow one to endow mapping spaces, quotients, and singular spaces smooth structure with (relative) ease.

###### Aristotelis Panagiotopoulos (UIUC Math)

Abstract: We are reading the paper 'Multiple recurrence in quasirandom groups' by Bergelson and Tao ( http://arxiv.org/abs/1211.6372 ).
