设Δ为嵌入r2中的连通的纯二维简单复合体,设C R (Δ})为光滑度R如[7]中Δ的均匀样条模。为了研究C r (Δ), Schenck和Stillman在[7]中开发了商复合物S•/J•。在[8]中,Schenck和Stiller推测h1 (S•/J•)的正则性小于2r + 1。在本文中,我们对这个“2r + 1”猜想提出了一个反例。我们还对这个猜想提出了一些修正。
Let Δ be a connected, pure 2-dimensional simplicial complex embedded in R 2 and let C r (Δ ˆ) be the homogenized spline module of Δ with smoothness r as in [7]. To study C r (Δ ˆ), Schenck and Stillman developed in [7] the quotient complex S•/J•. In [8], Schenck and Stiller conjectured that the regularity of H 1 (S•/J•) is less than 2 r+ 1. In this article, we pose a counterexample to this “2 r+ 1” conjecture. We also propose some modifications to the conjecture.
