It is well known that epimorphisms in rings do not have to be surjective.
Suppose C is a category and R is a ring object in C. I am looking for a
name to call maps X --> Y in C with the property that Hom(Y,R) -->
Hom(X,R) is epic in rings. It is a kind of weak R-injectivity. Does
anyone have a name for this?
Michael
