Is Homomorphism the Same Thing as Isomorphism?

An isomorphism is a special type of homomorphism. The Greek roots “homo” and “morph” together mean “same shape.” There are two situations where homomorphisms arise: when one group is a subgroup of another; when one group is a quotient of another. The corresponding homomorphisms are called embeddings and quotient maps.

Does homomorphism imply isomorphism?

In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). ... A homomorphism may also be an isomorphism, an endomorphism, an automorphism, etc.

What is homomorphism and isomorphism of group?

Isomorphism. A group homomorphism that is bijective; i.e., injective and surjective. Its inverse is also a group homomorphism. In this case, the groups G and H are called isomorphic; they differ only in the notation of their elements and are identical for all practical purposes.
