And that is just in math. (sigh...)
homomorphisms are simply looser isomorphisms as far as their cohort of objects in their particular category are concerned.
Maybe “ideal” has to do with rings of these beasties and what these homomorphisms change into nothingness, or at least the zero of the ring. Oops, the math is beginning to get political.
Homomorphisms. Homological algebra. Homology groups. Homotheties.
must be another gay agenda
