WebGroup cohomology is used in the fields of abstract algebra, homological algebra, algebraic topology and algebraic number theory, as well as in applications to group theory proper. … Webtheorem which determines cohomology groups with arbitrary coe cients from homology with Z coe cients. Remark 1.2.3. For non-abelian group G, we could still de ne (co)homology, but the point is that usually Hn(C;G) do not have a group structure when n>0, since Im need not to be a normal subgroup of ker . 1.3Universal Coe cient Theorem
