Two parameters circular ensembles and Jacobi-Trudi type formulas for Jack functions of rectangular shapes
نویسنده
چکیده
Jack function theory is useful for the calculation of the moment of the characteristic polynomials in Dyson’s circular β-ensembles (CβE). We define a q-analogue of the CβE and calculate moments of characteristic polynomials via Macdonald function theory. By this q-deformation, the asymptotics calculation of these moments becomes simple and the ordinary CβE case is recovered as q → 1. Further, by using a hyperdeterminant which is a simple generalization of a determinant, we give a Jacobi-Trudi type formula for Jack symmetric functions of rectangular shapes. MSC-class: primary 15A52; secondary 05E05.

Hyperdeterminantal expressions for Jack functions of rectangular shapes
We derive a Jacobi-Trudi type formula for Jack functions of rectangular shapes. In this formula, we make use of a hyperdeterminant, which is Cayley’s simple generalization of the determinant. In addition, after developing the general theory of hyperdeterminants, we give summation formulas for Schur functions involving hyperdeterminants, and evaluate Toeplitztype hyperdeterminants by using Jack ...

متن کاملLaplace-Beltrami operator for Jack polynomials
We introduce a Laplace-Beltrami type operator on the Fock space of symmetric functions and show that the Jack symmetric functions are the only family of eigenvectors of the differential operator, thus giving a new characterization of Jack polynomials. This was achieved by explicit computation of its action on generalized homogeneous symmetric functions. Using this new method we give a combinato...
متن کاملLattice Path Proofs for Determinantal Formulas for Symplectic and Orthogonal Characters
We give bijective proofs for Jacobi{Trudi-type and Giambelli-type identities for symplectic and orthogonal characters. These proofs base on interpreting King and El-Sharkaway's symplectic tableaux, Proctor's odd and intermediate symplectic tableaux, Proctor's and King and Welsh's orthogonal tableaux, and Sundaram's odd orthogonal tableaux in terms of certain families of nonintersecting lattice ...
متن کاملVibration Analysis for Rectangular Plate Having a Circular Central Hole with Point Support by Rayleigh-Ritz Method
In this paper, the transverse vibrations of rectangular plate with circular central hole have been investigated and the natural frequencies of the mentioned plate with point supported by Rayleigh-Ritz Method have been obtained. In this research, the effect of the hole is taken into account by subtracting the energies of the hole domain from the total energies of the whole plate. To determine th...
