Multiple orthogonal polynomials associated with the exponential integral
Walter Van Assche, Thomas Wolfs
We introduce a new family of multiple orthogonal polynomials satisfying orthogonality conditions with respect to two weights on the positive real line, with $w_1(x)=x^α…

Christoffel functions for multiple orthogonal polynomials
Grzegorz Świderski, Walter Van Assche
We study weak asymptotic behaviour of the Christoffel--Darboux kernel on the main diagonal corresponding to multiple orthogonal polynomials. We show that under some hypotheses the…
