On the geometry of nilpotent orbits
Web1 de jun. de 2008 · We first construct a deformation of the nilpotent orbit closure in a canonical manner, according to Brieskorn and Slodowy (see [S]), and next describe all its crepant simultaneous resolutions. This construction enables us to divide the whole space into a finite number of chambers. Moreover, by using this construction, one can … WebIn this paper we illustrate the importance of real nilpotent orbits by considering single-center solutions to a simple 4-dimensional model, namely the so-called STU model, see for instance [10, 20].We briefly provide the physical motivation for this problem (– referring to [] for a more detailed discussion of multi-center solutions –) and then attack it using a …

WebFor example, these orbits have a linear ordering with respect to the closure relation, and $ K_{\mathbb C} $ acts on them in multiplicity-free manner. We clarify the $ K_{\mathbb C} $ -module structure of the regular function ring of the closure of these nilpotent orbits in detail, and prove the normality. http://www2.math.umd.edu/~pbrosnan/Papers/zucker.pdf

The polarization is complex and in fact makes the orbit into a (positive) Kähler manifold. We study the geometry of this Kähler structure, the Vergne diffeomorphism, and the Hamiltonian functions giving the symmetry.
