Eilenberg-Mac Lane Space
For any Abelian Group 
and any Natural Number 
, there is a unique Space (up to Homotopy type)such that all Homotopy Groups except for the th are trivial (including the 0th HomotopyGroups, meaning the Space is path-connected), and the th Homotopy Group isIsomorphic to the Group . In the case where 
, the Group can benon-Abelian as well.
Eilenberg-Mac Lane spaces have many important applications. One of them is that every Topological Space has theHomotopy type of an iterated Fibration of Eilenberg-Mac Lane spaces (called a Postnikov System). Inaddition, there is a spectral sequence relating the Cohomology of Eilenberg-Mac Lane spaces to the HomotopyGroups of Spheres.
