摘要
Let I be an ideal of an integral domain T, let phi : T -> T/I be the projection, let D be an integral domain contained in T/I, and let R = phi(-1)(D). We characterize when R is an almost Prufer upsilon-multiplication domain, an almost valuation domain, and an almost Prufer domain, in the context of pullbacks.
