Schemes can keep track of infinitesimal information that varieties and algebraic cycles cannot. For example, if two points in a variety approach each other in an algebraic family, the limiting subvariety is a single point, the limiting algebraic cycle is a point with multiplicity 2, and the limiti… crypto whale trades

WebOct 1, 2024 · Abstract. We answer two questions of Carrell on a singular complex projective variety admitting the multiplicative group action, one positively and the other negatively. The results are applied to Chow varieties and we obtain Chow groups of 0-cycles and Lawson homology groups of 1-cycles for Chow varieties. A brief survey on the structure of ... 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).
