Piñeiro mixed orthogonal polynomials and bidiagonal factorization
Amílcar Branquinho, Juan E. F. Díaz, Ana Foulquié-Moreno +1
We study mixed multiple orthogonal polynomials associated with rank-one matrices of measures and their recurrence relations. On the step line we identify the corresponding banded r…

Multiple orthogonal polynomials: Pearson equations and Christoffel formulas
Amilcar Branquinho, Ana Foulquié-Moreno, Manuel Mañas
Multiple orthogonal polynomials with respect to two weights on the step-line are considered. A connection between different dual spectral matrices, one banded (recursion matrix) an…
