摘要:
LetIbe an ideal of a Noetherian ringRand letSbe a multiplicatively closed subset of R. We define the n-th (S)-symbolic power of 7 as S(In) = InRs∩R. The purpose of this paper is to compare the topologies defined by the adic {In}n≤0and the (S)-symbolic filtration {S(In)}n≥o using the direct system {ExtiR(R/In,R)}n≥0

摘要:
It is proved that certain polynomials of degree ≱3 have a cyclic group of order n as Galois group over all rational function fields k(t) with characteristic not dividing n. Moreover, the extension fields of k(t) generated by the polynomials have k as precise field of constants, and possess an unramified rational point. For all 3≤≰20 with the exceptions of 17 and 19 the polynomials are calculated explicitly
