Web1 The Hilbert scheme of points as a set There are several objects in mathematics which have the magical property of appearing in various areas and which are, therefore, of the greatest interest for mathematicians. One of those, of which we shall discuss in these notes, is the Hilbert scheme of points on a surface. WebHilbert scheme (or the Hilbert scheme of G-orbits) HilbG(Ar) is introduced by Ito and Nakamura [11]. The G-Hilbert scheme is the main component of the scheme parameterizing all G-invariant zero-dimensional subschemes Z of Ar of length m:= jGj for which H0(Z;OZ) is the regular representation of G.
