WebIn mathematics, particularly in the field of algebraic geometry, a Chow variety is an algebraic variety whose points correspond to effective algebraic cycles of fixed dimension and degree on a given projective space. More precisely, the Chow variety Gr ⁡ {\displaystyle \operatorname {Gr} } is the fine moduli variety parametrizing all effective algebraic cycles … WebJan 29, 2010 · (Only finitely many of the A D 's are needed, but it would be a little time consuming to say which ones.) The Hilbert scheme is the closure of S 0 in S × C P ∞. Algebraically, we can describe this as the blow up of S along the ideal generated by all products A D A D ′.

A more sophisticated solution to the problem of 'correctly' counting the degree of a degenerate subvariety is to work with subschemes of rather than subvarieties. 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… WebTheHilbert-Chow morphismand the incidence divisor In this section we deﬁne the Chow variety, the Hilbert-Chow morphism, and construct our proper hypercovering.
