Rational homotopy theory
In a sense, the main goal of algebraic topology is the creation of the algebraic description of the category of topological spaces and continuous maps up to homotopy. Rational homotopy theory, developed by Quillen and Sullivan, is a piece of topology where this main goal is completely achievable: homotopy theory of simply connected spaces whose higher homotopy groups are not just abelian groups, but vector spaces over Q, is completely described by their commutative differential graded algebras of cochains, in the sense that there is an equivalence of corresponding localized categories. The goal of this course is to describe this equivalence.

修课要求
Algebraic topology --- homotopy groups, homology groups, and the corresponding algebra. The familiarity with the theory of de Rham cohomology will be very helpful.

讲师介绍
I am mostly interested in the applications of homological algebra to the problems of geometry, in the broad sense.
