Analogues of the Capelli identity are given for every irreducible reductive dual pair in the complex symplectic group and the complex orthogonal group. They describe a natural correspondence between the “centers” of the two universal enveloping algebras and an algebra of invariant operators. 相似文献

Recent work in the formal calculus of variations and also in Riemannian geometry and general relativity have relied upon certain important, previously established properties of determinant ideals in characteristic zero. This note presents direct, elementary proofs of these properties by utilizing the Capelli identities of classical invariant theory. 相似文献

We extend the Capelli identity from the Lie algebra to the other classical Lie algebras and . We employ the theory of reductive dual pairs due to Howe. Received: 12 February 1997 / in revised form: 24 July 1998 相似文献

We consider some remarkable central elements of the universal enveloping algebraU(gl(n)) which we call quantum immanants. We express them in terms of generatorsE
ij ofU(gl(n)) and as differential operators on the space of matrices These expressions are a direct generalization of the classical Capelli
identities. They result in many nontrivial properties of quantum immanants.

By applying the theorem that every positive integer is a sum of four squares, we calculate the exponential growth of the codimensions
for the relatively free algebra satisfying Capelli identities.

extensions of the Mehta integral [5], [6].

Inspired by the Capelli-type identities for group determinants researched by Tôru Umeda, we give Capelli identities for irreducible representations of any finite group, and Capelli elements of the group algebra associated with these identities. These elements construct a basis of the centre of the group algebra. 相似文献

The asymptotic distribution of the Tukey median has recently been obtained by Nolan in a bivariate setting and by Bai and He in the general multivariate case. To establish their theorem, these authors made a strong symmetry hypothesis on the distribution and, in the case of Bai and He, assumed the existence of a density function with a gradient satisfying a finite-moment condition. This paper extends the above result by deriving the asymptotic distribution of the above location estimate without making any symmetry or differentiability assumption on the distribution. 相似文献
