On the homotopy category of Moore spaces and the cohomology of the category of abelian groups
Hans-Joachim Baues, Manfred Hartl (1996)
Fundamenta Mathematicae
Similarity:
The homotopy category of Moore spaces in degree 2 represents a nontrivial cohomology class in the cohomology of the category of abelian groups. We describe various properties of this class. We use James-Hopf invariants to obtain explicitly the image category under the functor chain complex of the loop space.
