Let H be a normal subgroup of G. Then γ: G → G / H given by γ(x) = xH is a homorphism with kernel H. My question is in proving that H is indeed the kernel of γ. It says:
WebIt follows that a homomorphism f is completely determined by the value f (1 mod 24). Write f (1 mod 24) = n mod 18 where n is an integer such that 0 ≤ n ≤ 17. Notice that 24n mod 18 = 24f (1 mod 24) = f (24 mod 24) = f (0 mod 24) = 0 mod 18. since any homomorphism maps the identity to identity. Web10 okt. 2024 · A map ϕ: G → H is called a homomorphism if ϕ(xy) = ϕ(x)ϕ(y) for all x, y in G. A homomorphism that is both injective (one-to-one) and surjective (onto) is called an isomorphism of groups. If ϕ: G → H is an isomorphism, we say that G is isomorphic to …

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. myer tommy bahamaWeb31 dec. 2016 · The multiplicative group of Z / 15 Z is abelian so there exists a homomophism to the subgroup consisting of the squares of elements: it is simply the map x ↦ x 2, as was pointed out in the comments.
