چکیده
Such identities arise in Rankin-Selberg integral representations of L-functions. For GL2, a naive, direct computation is sufficient. However, for general GLn and other higher-rank groups, direct computation is inadequate. Further, connecting local Rankin-Selberg computations to Schur functions usefully connects these computations to the Shintani-Casselman-Shalika formulas for spherical p-adic Whittaker functions.

A Proof of Stanley’s Open Problem
In the open problem session of the FPSAC’03, R.P. Stanley gave an open problem about a certain sum of the Schur functions (See [19]). The purpose of this paper is to give a proof of this open problem. The proof consists of three steps. At the first step we express the sum by a Pfaffian as an application of our minor summation formula ([7]). In the second step we prove a Pfaffian analogue of Cau...
متن کاملA Robinson-schensted-knuth Type Correspondence Related to Schubert Polynomials and Its Applications
We present an analog of the Robinson-Schensted-Knuth correspondence which bijectively proves the Cauchy identity for Schubert polynomials; thus, it generalizes the classical correspondence, which proves the similar identity for Schur functions. Our correspondence is based on a new insertion procedure for certain binary tableaux of staircase shape, which are the analogs of semistandard Young tab...

متن کاملLattice Paths and the Flagged Cauchy Determinant
We obtain a flagged form of the Cauchy determinant and establish a correspondence between this determinant and nonintersecting lattice paths, from which it follows that Cauchy identity on Schur functions. By choosing different origins and destinations for the lattice paths, we are led to an identity of Gessel on the Cauchy sum of Schur functions in terms of the complete symmetric functions in t...
متن کاملA plactic algebra of extremal weight crystals and the Cauchy identity for Schur operators
We give a new bijective interpretation of the Cauchy identity for Schur operators which is a commutation relation between two formal power series with operator coefficients. We introduce a plactic algebra associated with the Kashiwara’s extremal weight crystals over the Kac–Moody algebra of type A+∞, and construct a Knuth type correspondence preserving the plactic relations. This bijection yiel...
