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.
