El Departamento de Análisis Matemático y  el Instituto de Matemáticas y Aplicaciones de la Universidad de La Laguna organizan Seminarios de Análisis Matemático y Matemática Aplicada con carácter semanal.Conferenciante: Marcus Vaktnäs (Uppsala U., Suecia) Multiple orthogonal polynomials extend the notion of orthogonal polynomials, allowing broader applications to e.g. rational approximation, numerical integration, and random matrix theory. These polynomials have been studied extensively over the last few decades, but nearly all of this research concerns orthogonality with respect to measures supported on…
