Some Results on Betti Series of Universal Modules of Differential Operators. (arXiv:1705.06129v1 [math.AC])
来源于:arXiv
In this article, we discuss the rationality of the Betti Series of the
universal module of nth order derivations of R_{m} where m is a maximal ideal
of R. We proved that if R is a coordinate ring of an affine irreducible curve
and if it has at most one singularity point, then the Betti series is rational. 查看全文>>
