Completions of subcategories of domains

This is joint work with John Kennison and Bob Raphael. We have been studying the limit completion, in the category of commutative rings, of various subcategories of integral domains. Since any limit of domains is a semiprime ring (only nilpotent is 0), we will concentrate on the limit closure in that subcategory. This will complement the talk Bob is giving on Sept. 16.
