I wish to study the book on Homological Algebra by Weibel but am not sure of the prerequisites. In particular how much category theory is assumed on the part of the reader ?
Would prerequisites for Rotman's book be lesser ? Should I prefer Rotman's book over Weibel's ?
I am more interested in applying Homological Algebra to Topology & Geometry rather than other applications.
My background is 1 year graduate course on Algebra based on Lang covering Groups, Rings, Modules, Fields & Galois Theory and basics of Homological Algebra. I do not know any algebraic topology beyond the definition of fundamental group. But I do not mind postponing understanding the motivation for some concepts of Homological Algebra that may have origin in Topology.
