Homotopy Groups

Abstract

In Chapter III we saw that, if X is any space with base point, then π n (X) = [S n , X] is a group for any positive integer n. In fact, n n is a functor from the category K 0 to the category of groups if n = 1, abelian groups if n > 1. In certain respects, they resemble the homology groups, and one of the objectives of this chapter is to pursue this analogy and see where it may lead.
