Onto homomorphism
WebHomomorphism between groups. A group homomorphism from a group ( G, *) to a group ( H, #) is a mapping f : G → H that preserves the composition law, i.e. for all u and v in G one has: f ( u * v) = f ( u) # f ( v ). A homomorphism f maps the identity element 1 G of G to the identity element 1 H of H, and it also maps inverses to inverses: f ...
