Orthogonal Basic Hypergeometric Laurent Polynomials

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The Askey-Wilson polynomials are orthogonal polynomials in$x = cos heta$, which are given as a terminating $_4phi_3$ basic hypergeometric series. The non-symmetric Askey-Wilson polynomials are Laurent polynomials in $z=e^{iheta}$, which are given as a ...

Bispectrality of the Complementary Bannai-Ito Polynomials

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
A one-parameter family of operators that have the complementary Bannai-Ito (CBI) polynomials as eigenfunctions is obtained. The CBI polynomials are the kernel partners of the Bannai-Ito polynomials and also correspond to a q→−1 limit of the Askey-Wilson ...

Nevanlinna Theory of the Wilson Divided-difference Operator [PDF]

open access: yesAnn. Acad. Sci. Fenn. Math. 42, 175-209 (2017), 2016
Sitting at the top level of the Askey-scheme, Wilson polynomials are regarded as the most general hypergeometric orthogonal polynomials. Instead of a differential equation, they satisfy a second order Sturm-Liouville type difference equation in terms of the Wilson divided-difference operator.

Two-Variable Wilson Polynomials and the Generic Superintegrable System on the 3-Sphere

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
We show that the symmetry operators for the quantum superintegrable system on the 3-sphere with generic 4-parameter potential form a closed quadratic algebra with 6 linearly independent generators that closes at order 6 (as differential operators ...

On Solutions of Holonomic Divided-Difference Equations on Nonuniform Lattices

open access: yesAxioms, 2013
The main aim of this paper is the development of suitable bases that enable the direct series representation of orthogonal polynomial systems on nonuniform lattices (quadratic lattices of a discrete or a q-discrete variable). We present two bases of this

Exact results and Schur expansions in quiver Chern-Simons-matter theories

open access: yesJournal of High Energy Physics, 2020
We study several quiver Chern-Simons-matter theories on the three-sphere, combining the matrix model formulation with a systematic use of Mordell’s integral, computing partition functions and checking dualities.

Bethe Ansatz Solutions to Quasi Exactly Solvable Difference Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Bethe ansatz formulation is presented for several explicit examples of quasi exactly solvable difference equations of one degree of freedom which are introduced recently by one of the present authors.

Dynamics of black holes in Jackiw-Teitelboim gravity

open access: yesJournal of High Energy Physics, 2020
We present a general solution for correlators of external boundary operators in black hole states of Jackiw-Teitelboim gravity. We use the Hilbert space constructed using the particle-with-spin interpretation of the Jackiw-Teitelboim action, which ...

Infinitely many shape invariant discrete quantum mechanical systems and new exceptional orthogonal polynomials related to the Wilson and Askey-Wilson polynomials [PDF]

open access: yesPhys. Lett. B682 (2009) 130-136, 2009
Two sets of infinitely many exceptional orthogonal polynomials related to the Wilson and Askey-Wilson polynomials are presented. They are derived as the eigenfunctions of shape invariant and thus exactly solvable quantum mechanical Hamiltonians, which are deformations of those for the Wilson and Askey-Wilson polynomials in terms of a degree \ell (\ell ...
