Multiple orthogonal polynomial ensembles of derivative type
Thomas Wolfs
We characterize the biorthogonal ensembles that are both a multiple orthogonal polynomial ensemble and a polynomial ensemble of derivative type (also called a Pólya ensemble). We…

Rational approximation of Euler's constant using multiple orthogonal polynomials
Thomas Wolfs, Walter Van Assche
We construct new rational approximants of Euler's constant that improve those of Aptekarev et al. (2007) and Rivoal (2009). The approximants are given in terms of certain (mixed ty…
