Infinity Seminar

The Infinity Seminar is a learning seminar about (∞,1)-categories and Derived Algebraic Geometry. The plan for this term is to start with a review of classical stacks and the étale and fpqc sites, then talk about algebraic stacks over commutative rings. After that, we will discuss ∞-stacks, simplicial presheaves and try to understand derived stacks over the étale site for connective Ei∞ rings in various stable categories (spectra, Hk-modules, and so on).
