Jun 2, 2021 at 16:58 comment added Salvo Tringali Fine, I'll not use "hopfian" for my purposes. As for your 2nd comment, I really meant "eversible" (not "reversible").
Jun 2, 2021 at 16:25 comment added Benjamin Steinberg Left reversible also has another meaning in semigroup theory that is well established.
Jun 2, 2021 at 16:25 comment added Benjamin Steinberg Hopfian monoid has a different well established meaning so please don't use it. With your definition all groups are Hopfian. A monoid is Hopfian if every surjective monoid homomorphism is injective.
