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… WebIn Paper III, the relation between the Hilbert scheme of points, the symmetric product, the space of divided powers and the Chow variety of zero-cycles is studied. It is shown that all four of these schemes coincide over the locus parameterizing non-degenerate families and it is shown that the last three schemes coincide as topological spaces.

WebExecutive summary: If you look at the whole Hilbert scheme associated to a given polynomial, the locus of points corresponding to nonsingular (which I take to mean smooth) subschemes can sometimes be very small in terms of dimension and number of irreducible components.
