DOI: 10.1016/j.nuclphysb.2019.114824
Abstract: Abstract An operator of Heun-Askey-Wilson type is diagonalized within the framework of the algebraic Bethe ansatz using the theory of Leonard pairs. For different specializations and the generic case, the corresponding eigenstates are constructed in… read more here.

DOI: 10.1088/1751-8121/abd783
Abstract: The original Askey–Wilson algebra introduced by Zhedanov encodes the bispectrality properties of the eponym polynomials. The name Askey–Wilson algebra is currently used to refer to a variety of related structures that appear in a large… read more here.
