A quadratic inequality for sum of co-adjoint orbits
We obtain an e¤ective lower bound on the distance of sum of coadjoint orbits from the origin. Even when the distance is zero, thus the symplectic quotient is well-de ned, our result give a nontrivial constraint on these co-adjoint orbits. In the particular case of unitary groups, we recover the quadratic inequality for eigenvalues of Hermitian matrices satisfying A+B = C: This quadratic inequal...
متن کاملFusion Product of Co-adjoint Orbits
In this paper, we introduce the fusion product of a generic pair of co-adjoint orbits. This construction provides the geometric dual object to the product in Verlinde fusion algebra. The latter is a quantum deformation of the standard tensor product, the fusion product constructed here is the corresponding deformation of the Cartesian product. Let G be a connected and simply-connected compact s...
متن کاملInverse moment problem for elementary co-adjoint orbits
We give a solution to the inverse moment problem for a certain class of Hessenberg and symmetric matrices related to integrable lattices of Toda type.
متن کاملQuantum Co-adjoint Orbits of the Real Diamond Group
We present explicit formulas for deformation quantization on the coadjoint orbits of the real diamond Lie group. From this we obtain quantum halfplans, quantum hyperbolic cylinders, quantum hyperbolic paraboloids via Fedosov deformation quantization and finally, the corresponding unitary representations of this group.
متن کاملSums of Adjoint Orbits
We show that the sum of two adjoint orbits in the Lie algebra of an exponential Lie group coincides with the Campbell-Baker-Hausdorff product of these two orbits. Introduction N. Wildberger and others have recently investigated the structure of the hypergroup of the adjoint orbits in relation with the class hypergroup of compact Lie groups. A generalization of the notion of this type of hypergr...
