An orthogonality relation for multivariable Bessel polynomials
Martin Hallnäs
In a recent paper we introduced a multivariable generalisation of the Bessel polynomials, depending on one extra parameter, and related to the so-called hyperbolic Sutherland model…

Multivariable Bessel polynomials related to the hyperbolic Sutherland model with external Morse potential
Martin Hallnäs
A multivariable generalisation of the Bessel polynomials is introduced and studied. In particular, we deduce their series expansion in Jack polynomials, a limit transition from mul…
