Hilbert scheme to chow variety
WebApr 18, 2024 · The Quot scheme in question parametrizes quotient sheaves of O_X^d of length n supported at p, where p is a cusp singularity on a curve X; the Hilbert scheme is the special case d=1. Our method is based on a stratification given by Gröbner bases for power series ring (a.k.a. standard bases). Webif the Chow variety [10] of A is connected (see Corollary 4.9 in [16]). The same question for the toric Hilbert scheme [13, 14, 19] of the point set is not clear, even if Sturmfels and Haiman [7] have recently constructed a natural morphism from the toric Hilbert scheme to the toric Chow variety, because this morphism is in general not surjective.
