Only this year
ln this course we will develop algebraic and coalgebraic models for homotopy types. Among other things we will learn about Quillen's and Sullivan's model of rationâl homotopy types and about Mandell's theorem in p-adic homotopy theory.
We will start with an introduction to rational homotopy theory and prove Quillen's and Sullivan's theorem providing a Lie model, coalgebra model and algebra model for rational homotopy types. Moreover we will learn about Koszul duality relating the Lie model to the coalgebra model.
We will continue with p-adic homotopy theory and prove Mandell's theorem classifying p-adic homotopy types by E_infinity-algebras.
To prove Mandell's theorem we will learn about E_infinity-algebras and unstable algebras.
Besides that we will learn about the higher algebra and higher category theory used to prove these results.
