Curves in the complex plane that satisfy the S-property were first introduced by Stahl and
they were further studied by Gonchar and Rakhmanov in the 1980s. Rakhmanov recently …

This survey considers multiple orthogonal polynomials with respect to Nikishin systems
generated by a pair $(\sigma_1,\sigma_2) $ of measures with unbounded supports …

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 introduce a new family of special functions, namely $ q $-Charlier multiple orthogonal
polynomials. These polynomials are orthogonal with respect to $ q $-analogues of Poisson …

We discuss an application of the Mhaskar–Saff functional to the problem of location of the
hyperbolic shocks in the context of completely integrable approximations to nonlinear …

We consider two families of type II multiple orthogonal polynomials. Each family has
orthogonality conditions with respect to a discrete vector measure. The r components of …

Recurrence relations generating Padé and Hermite-Padé polynomials are considered. Their
coefficients increase with the index of the relation, but after dividing by an appropriate power …

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 …

В работе рассматриваются совместно ортогональные многочлены по отношению к
системам Никишина, генерируемым двумя мерами (σ1, σ2) с неограниченными …

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 …
