Discrete orthogonal matrices have applications in information coding and cryptography. It is
often challenging to generate discrete orthogonal matrices. A common approach widely in …

We study two families of type II discrete multiple orthogonal polynomials on an-legged star-
like set with respect to weight functions of Charlier (Poisson distributions) and Meixner …

We study a family of type II multiple orthogonal polynomials. We consider orthogonality
conditions with respect to a vector measure, in which each component is aq-analogue of the …

We study two families of type II discrete multiple orthogonal polynomials on an $ r $-legged
star-like set with respect to $ r $ weight functions of Charlier (Poisson distributions) and …

This paper studies a new family of Angelesco multiple orthogonal polynomials with shared
orthogonality conditions with respect to a system of weight functions, which are complex …
