摘要

设k是一个奇特征p的域,固定p的偶数d<;p+1和幂q≥d+3。对于大多数具有齐次极大理想m的d次标准分级超曲面R=k[x,y,z]/(f)的选择,我们可以确定R/m[q]的分级Betti数。事实上,给定两个固定的幂q0,q1≥d+3,对于大多数R的选择,R/m[q0]与R/m[q1]的高同次次的分级Betti数直到一个常数的位移是相同的。本文通过将我们的结果与Miller, Rahmati和R.G.关于[13]中链路-q压缩多项式的工作相结合来证明这一事实。我们证明了链路q压缩多项式在许多多项式环中确实是相当普遍的。

Determining the Betti numbers of R/(xpe,ype,zpe) for most even degree hypersurfaces in odd characteristic
Let k be a field of odd characteristic p. Fix an even number d<p+1 and a power qd+3 of p. For most choices of degree d standard graded hypersurfaces R=k[x,y,z]/(f) with homogeneous maximal ideal m, we can determine the graded Betti numbers of R/m[q]. In fact, given two fixed powers q0,q1d+3, for most choices of R the graded Betti numbers in high homological degree of R/m[q0] and R/m[q1] are the same up to a constant shift. This paper shows this fact by combining our results with the work of Miller, Rahmati, and R.G. on link-q-compressed polynomials in [13]. We show that link-q-compressed polynomials are indeed fairly common in many polynomial rings.

期刊介绍: The Journal of Pure and Applied Algebra concentrates on that part of algebra likely to be of general mathematical interest: algebraic results with immediate applications, and the development of algebraic theories of sufficiently general relevance to allow for future applications.
