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… WebIt turns out that there is a k-variety Chowm(X), called the Chow variety of X whose points are in “natural” one-to-one correspondence with the set of effective ...
