Epimorphic regular contexts

Robert Raphael

A von Neumann regular extension of a semiprime ring naturally defines a epimorphic extension in the category of rings. These are studied, and four natural examples are considered, two in commutative ring theory, and two in rings of continuous functions.

Keywords: epimorphism, von Neumann regular.
