On chained overrings of pseudo-valuation rings

Abstract

A prime ideal P of a commutative ring R with identity is called strongly prime if aP and bR are comparable for every a, b in R. If every prime ideal of R is strongly prima, then R is called a pseudo-valuation ring. It is well-known that a (valuation) chained overring of a Prufer domain R is of the form R, for some prime ideal P of R. In this paper, we show that this statement is valid for a certain class of chained overrings of a pseudo-valuation ring.
