Fast measure modification of orthogonal polynomials via matrices with displacement structure

Karim Gumerov, Samantha Rigg, Richard Mikael Slevinsky

It is well known that matrices with low Hessenberg-structured displacement rank enjoy fast algorithms for certain matrix factorizations. We show how n×n principal finite se…

Building hierarchies of semiclassical Jacobi polynomials for spectral methods in annuli

Ioannis P. A. Papadopoulos, Timon S. Gutleb, Richard M. Slevinsky +1

We discuss computing with hierarchies of families of (potentially weighted) semiclassical Jacobi polynomials which arise in the construction of multivariate orthogonal polynomials.…
