WebTools. In algebraic topology, a branch of mathematics, a spectrum is an object representing a generalized cohomology theory. Every such cohomology theory is representable, as follows from Brown's representability theorem. This means that, given a cohomology theory. , there exist spaces such that evaluating the cohomology theory in degree on a ... WebThe cup product is a family of maps from H p ( G, A) ⊗ H p ( G, B) → H p ( G, A ⊗ B) for all A, B and all non-negative integers p, q (for Tate cohomology, put hats on all the H 's and allow p, q to be arbitrary integers). (i) These homomorphisms are functorial in A and B.
