On the geometry of nilpotent orbits
WebThis occurs in the context of hyperkähler geometry. 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. We indicate how all this fits into a quantization program. Webone to these orbits (e.g., the Springer correspondence with representations of the Weyl group). In this note we announce new results concerning the symplectic and algebraic …

WebNilpotent orbits are finite in number. The Zariski closure of a nilpotent orbit is a union of nilpotent orbits. Jacobson–Morozov theorem: over a field of characteristic zero, any nilpotent element e can be included into an sl 2-triple {e,h,f} and all such triples are conjugate by Z G (e), the centralizer of e in G.
