Hilbert schemes of abelian group orbits

WebJul 28, 2009 · Let G be a polyhedral group, namely a finite subgroup of SO (3). Nakamura’s G -Hilbert scheme provides a preferred Calabi-Yau resolution Y of the polyhedral singularity ℂ 3 / G. The classical McKay correspondence describes the classical geometry of Y in terms of the representation theory of G.

Webthrough the theory of Hilbert scheme of group orbits. For a linear special group G acting on C n, we study the G-Hilbert scheme, HilbG(Cn), and crepant resolutions of C /G for G=the A-type abelian group A r(n). For n = 4, we obtain the explicit structure of HilbA r(4)(C4). The crepant resolutions of C4/A http://export.arxiv.org/abs/0712.2892

Webform has only zeros on the diagonal. In this case, the nilpotent orbits are classified by partitions of n, given by the sizes of the Jordan blocks.) The closures of the nilpotent orbits are singular in general, and understanding their singularities is an important problem. - The classification of irreducible Weyl group representations is quite old.
