Title：A brief introduction to diffeological spaces
Abstract：Diffeology uses (concrete) sheaf theory instead of local models to unify smooth manifolds, infinite dimensional spaces and singular spaces. The category of diffeological spaces is very convenient for doing various constructions. Furthermore, on each such space, one can still do differential topology/geometry in certain extent. I will give a brief overview of the basic theory and examples, and discuss some problems I am currently working on.
