In abstract algebra, a normal subgroup is a subgroup which is invariant under conjugation by members of the group of which it is a part. In other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.Normal subgroups (and only normal subgroups) can be used to construct quotient groups from a given group.n other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.
The kernel of h is a normal subgroup of G and the image of h is a subgroup of H : If and only if ker(h) = {eG }, the homomorphism, h, is a group monomorphism; i.e., h is injective (one-to-one).Injection directly gives that there is a unique element in the kernel, and a unique element in the kernel gives injection:nd the image of h to be. The kernel and image of a homomorphism can be interpreted as measuring how close it is to being an isomorphism. The First Isomorphism Theorem states that the image of a group homomorphism, h (G) is isomorphic to the quotient group G /ker h.
