Abstract:

The intent of this paper is to present a set of axioms that are sufficient for a closure operation to generate a balanced big Cohen-Macaulay module $B$ over a complete local domain $R$. Conversely, we show that if such a $B$ exists over $R$, then there exists a closure operation that satisfies the given axioms.
