| 概要 | Let G be a connected reductive complex algebraicc group, (G,K) a symmetric pair, and g = k + s denote the associated Cartan decomposition. We call an orbit on the set N_s of the nilpotent elements in s a nilpotent orbit of symmetric pair. As to the nilpotent orbits of symmetric pair, we talks about:
(1) the generating function of the number of the nilpotent orbits (2) the graph of adjacent relations of codimension one (3) associated varieties of irreducible H-C modules and adjacent relations |
