Title: The first few stable homotopy groups of spheres

Abstract:

We will present the "method of killing homotopy groups" due to Cartan and Serre in the 1950s, a method to compute some homotopy groups of spheres. The method relies on the Hurewicz theorem and the Serre spectral sequence of the fibration that kills the bottom homotopy group of a space.
