Let R be a commutative ring, we say that 𝒜Spec(R) has prime avoidance property, if I P𝒜P for an ideal I of R, then there exists P 𝒜 such that I P. We exactly determine when 𝒜Spec(R) has prime avoidance property. In particular, if 𝒜 has prime avoidance property, then 𝒜 is compact. For certain classical rings we show the converse holds (such as Bezout rings, QR-domains, zero-dimensional rings and C(X)). We give an example of a compact set 𝒜Spec(R), where R is a Prufer domain, which has not prime avoidance property. Finally, we show that if V,V1,,Vn are valuation domains for a field K and V [x] i=1nV i for some x K, then there exists v V such that v + xi=1nV i.

质数回避性质

R是一个交换环,我们说𝒜规格(R)具有主要回避属性,如果一世 𝒜为了一个理想一世R, 那么存在 𝒜这样一世 . 我们确切地确定何时𝒜规格(R)具有主要的回避属性。特别是,如果𝒜有主要的回避性质,那么𝒜紧凑。对于某些经典戒指,我们展示了相反的情况(例如 Bezout 戒指,R-域,零维环和C(X))。我们举一个紧集的例子𝒜规格(R), 在哪里R是一个 Prufer 域,它没有主要的回避属性。最后,我们证明如果,1,,n是字段的评估域ķ [X] 一世=1n 一世对于一些X ķ, 那么存在v 这样v + X一世=1n 一世.
