SAMMANFATTNING
Originally the Euler characteristic was defined by triangulation and
Eulers formula. The Euler characteristic is a homotopy invariant. The
reason for this is that the Euler characteristic also can be computed
using homology groups. In this essay we describe the connection
between these two means of calculating the Euler characteristic. Basic
concepts in homological algebra and homotopy theory are
discussed. This essay is a sequel to my earlier essay Euler och
hans matematik.
