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…
