I. Generalizations of the Capelli and Turnbull identities

Noncommutative determinants, Cauchy-Binet formulae, and Capelli-type identities I. Generalizations of the Capelli and Turnbull identities

We prove, by simple manipulation of commutators, two noncommutative generalizations of the Cauchy–Binet formula for the determinant of a product. As special cases we obtain elementary proofs of the Capelli identity from classical invariant theory and of Turnbull’s Capelli-type identities for symmetric and antisymmetric matrices.

Factorial Supersymmetric Schur Functions and Super Capelli Identities

AND SUPER CAPELLI IDENTITIES Alexander Molev Centre for Mathematics and its Applications, Australian National University, Canberra, ACT 0200, Australia (e-mail: [email protected]) Abstract A factorial analogue of the supersymmetric Schur functions is introduced. It is shown that factorial versions of the Jacobi{Trudi and Sergeev{Pragacz formulae hold. The results are applied to construct a ...

Capelli Identities for Classical Lie Algebras

We extend the Capelli identity from the Lie algebra glN to the other classical Lie algebras soN and spN . We employ the theory of reductive dual pairs due to Howe.
