A family of Nikishin systems with periodic recurrence coefficients
Steven Delvaux, Abey López García, Guillermo López Lagomasino
Suppose we have a Nikishin system of measures with the th generating measure of the Nikishin system supported on an interval $Δ_k\subset\er$ with …
Zeros and ratio asymptotics for matrix orthogonal polynomials
Steven Delvaux, Holger Dette
Ratio asymptotics for matrix orthogonal polynomials with recurrence coefficients and having limits and respectively (the matrix Nevai class) were obtained by Du…
Non-intersecting squared Bessel paths with one positive starting and ending point
Steven Delvaux, Arno B. J. Kuijlaars, Pablo Román +1
We consider a model of non-intersecting squared Bessel processes with one starting point at time t=0 and one ending point at time . After proper scaling, the p…
Equilibrium problem for the eigenvalues of banded block Toeplitz matrices
Steven Delvaux
We consider banded block Toeplitz matrices with block rows and columns. We show that under certain technical assumptions, the normalized eigenvalue counting measure of $T…
