[HTML][HTML] Fast and reliable algorithms for computing the zeros of Althammer polynomials
T Laudadio, N Mastronardi, P Van Dooren - Applied Numerical …, 2025 - Elsevier
In this manuscript, we propose a stable algorithm for computing the zeros of Althammer
polynomials. These polynomials are orthogonal with respect to a Sobolev inner product, and …
