Thank you very much for your kind and very clear answer about isomorphism. Now, if i understand well, homomorphic means the same structure and isomorphic means an equal structure. Is there any way to name the identity, the relation between something and itself? I mean, "homo" and "iso"...
I am sorry to jump in by a very elementary question: is there a way to explain with non-mathematical examples the concept of iso- and homo- morphism? Or to downgrade the level of the mathematical explanation so as to fit brains that are slightly poor in its understanding capabilities for this...
