WebIntuition. The purpose of defining a group homomorphism is to create functions that preserve the algebraic structure. An equivalent definition of group homomorphism is: … 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 ...

Web7.2: Ring Homomorphisms. As we saw with both groups and group actions, it pays to consider structure preserving functions! Let R and S be rings. Then ϕ: R → S is a homomorphism if: ϕ is homomorphism of additive groups: ϕ ( a + b) = ϕ ( a) + ϕ ( b), and. ϕ preserves multiplication: ϕ ( a ⋅ b) = ϕ ( a) ⋅ ϕ ( b). WebProve the function is a homomorphism: Once you have verified that the function f is well-defined and preserves the group operation, you can prove that it is a homomorphism by showing that it is both injective (one-to-one) and surjective (onto). If you can find a function that satisfies all of these conditions, ...
