Another way to think about it is that a homomorphism is a map that commutes with multiplication, addition, scaling - or whatever operations characterize your algebraic object. This is actually almost …

Bijectivity is a great property, which allows to identify (up to isomorphisms!) the given groups. Moreover, a bijective homomorphism of groups $\varphi$ has inverse $\varphi^ {-1}$ which is automatically a …

Apr 2, 2016 · I was wondering if someone could explain the ideas behind isomorphisms and homomorphisms and the difference between them. I understand that a linear map is an isomorphism …

Oct 30, 2018 · The definition is, it's the image of the field under a homomorphism. So: do you know what field means? do you know what image means? do you know what homomorphism means?

Mar 8, 2026 · Each isomorphism has an inverse, which is also an isomorphism between the groups. So yes: "being isomorphic" goes beyond the isomorphism in that strict sense. What we mean when we …

Jan 10, 2020 · Thanks for the links, but I saw this question already didnt understand a thing in it, the answers given were a bit complex for me, because i dont really know how to use relations to find …

Sep 21, 2021 · If $G$ is a solvable group, then every homomorphic image of $G$ is solvable (Fundamentals of Abstract Algebra by D.S. Malik, John M. Mordeson, M. K. Sen, page 229, 230).

"How are homomorphic images and homomorphisms different?" For starters a homomorphism is a function, while homomorphic image a subset. Have you looked at definitions? What exactly is the …
