On absolutely CR-epic spaces.
Abstract: A completely regular space X is called absolute CR-epic if whenever X is embedded into another completely regular space Y, the induced map C(Y) --> C(X) is an epimorphism in the category CR of commutative rings. For example, every space that is locally compact and sigma-compact is an absolute CR-epic. This is joint work with Robert Raphael and Grant Woods.
