Determinantal Forms for Symplectic and Orthogonal Schur Functions
نویسنده
چکیده
Symplectic and orthogonal Schur functions can be defined combinatorially in a manner similar to the classical Schur functions. This paper demonstrates that they can also be expressed as determinants. These determinants are generated using planar decompositions of tableaux into strips and the equivalence of these determinants to symplectic or orthogonal Schur functions is established by Gessel-Viennot lattice path techniques. Results for rational (also called composite) Schur functions are also obtained. MR Classification Number: Primary 05E05, Secondary 05El0, 20C33.

Lattice 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 کاملThe Flagged Double Schur Function
The double Schur function is a natural generalization of the factorial Schur function introduced by Biedenharn and Louck. It also arises as the symmetric double Schubert polynomial corresponding to a class of permutations called Grassmannian permutations introduced by A. Lascoux. We present a lattice path interpretation of the double Schur function based on a flagged determinantal definition, w...
متن کاملHook-content Formulae for Symplectic and Orthogonal Tableaux
By considering the specialisation sλ(1, q, q , . . . , q) of the Schur function, Stanley was able to describe a formula for the number of semistandard Young tableaux of shape λ in terms of two properties of the boxes in the diagram for λ. Using specialisations of symplectic and orthogonal Schur functions, we derive corresponding formulae, first given by El Samra and King, for the number of semi...
متن کاملVertex Operator Realization of Symplectic and Orthogonal S-functions
It is shown that symplectic and orthogonal Schur functions can be realized by the action of the modes of certain vertex operators on the function 1. The properties of these vertex operators allow one to reproduce the basic propreties of these types of symmetric functions. The vertex operator modes are shown to obey free fermionic relations which provides applications such as calculating product...
متن کاملAverages of Characteristic Polynomials in Random Matrix Theory
We compute averages of products and ratios of characteristic polynomials associated with Orthogonal, Unitary, and Symplectic Ensembles of Random Matrix Theory. The pfaffian/determinantal formulas for these averages are obtained, and the bulk scaling asymptotic limits are found for ensembles with Gaussian weights. Classical results for the correlation functions of the random matrix ensembles and...
