Zeros of Multiple Orthogonal Polynomials: Location and Interlacing

Rostyslav Kozhan, Marcus Vaktnäs

We prove a criterion on the possible locations of zeros of type I and type II multiple orthogonal polynomials in terms of normality of degree Christoffel transforms. We provide…

Christoffel Transform and Multiple Orthogonal Polynomials

Rostyslav Kozhan, Marcus Vaktnäs

We investigate multiple orthogonal polynomials associated with the system of measures obtained by applying a Christoffel transform to each of the orthogonality measures. We present…
