Abstract:
In this paper, we introduce the concept of Essentially Powers Bifiltraton EP bifiltration for short (EP bifiltration for short) and then, starting from a given bifiltration F on a commutative ring A, we determine a bifiltration H on A which is an EP bifiltration. We deduce a necessary and sufficient condition for the bifiltrations in some class to be EP.
