# Graduate Topology Seminar 2019, I: Rational Homotopy Theory

The aim of the graduate topology seminar of semester 1, 2019 is to understand the basics of rational homotopy theory. Participants are expected to have basic knowledge on simplicial and singular (co)homology, and know the definition of higher homotopy groups. Knowledge on de Rham cohomology is very helpful, but not necessary.
