Inverse limits of Macaulay's inverse systems. (arXiv:1803.06215v1 [math.AC])
来源于:arXiv
Generalizing a result of Masuti and the second author, we describe inverse
limits of Macaulay's inverse systems for Cohen-Macaulay factor algebras of
formal power series or polynomial rings over an infinite field. On the way we
find a strictness result for filtrations defined by regular sequences. It
generalizes both a lemma of Uli Walther and the Rees isomorphism. 查看全文>>
