WebIf we know that there's a group homomorphism ϕ: G → H, then the kernel of ϕ consists precisely of those elements of G that we "forget" in H via ϕ. The quotient group G / ker ( ϕ) essentially forgets these elements as well. So, if N ⊆ ker ( ϕ), then specifying a group homomorphism G / N → H just amounts to forgetting fewer elements which we can do.
