Positivity of Gibbs states on distance-regular graphs
Michael Voit
We study criteria which ensure that Gibbs states (often also called generalized vacuum states) on distance-regular graphs are positive. Our main criterion assumes that the graph ca…
Distances of roots of classical orthogonal polynomials
Michael Voit
Let one of the classical sequences of orthogonal polynomials, i.e., Hermite, Laguerre or Jacobi polynomials. For the roots of we der…
Elementary symmetric polynomials and martingales for Heckman-Opdam processes
Margit Rösler, Michael Voit
We consider the generators of Heckman-Opdam diffusion processes in the compact and non-compact case in dimensions for root systems of type and , with a multiplicit…
