Orthogonal polynomials for the singularly perturbed Laguerre weight, Hankel determinants and asymptotics

Chao Min, Xiaoqing Wu

Based on the work of Chen and Its [{\em J. Approx. Theory} {\bf 162} ({2010}) {270--297}], we further study orthogonal polynomials with respect to the singularly perturbed Laguerre…
