WebIn algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The … Webp) stand for the connecting homomorphism of degree 0 coming from the rightmost vertical sequence, and letting δi: Hi(D,Qp) →Hi+1(D,Qp(1)) be the connecting homomorphism of degree iassociated to the bottom row and the top row. By the commutativity of the diagram, we get the following commutative square: H0(D,Q p)=Qp −−−→δ0 H1(D,Q p(1 ...
