Selfadjoint Jacobi matrices on graphs and multiple orthogonal polynomials
Selfadjoint operators on the graph-trees are constructed by means of the difference equations connecting nearest neighbors in the lattice of multiple orthogonal polynomials. This construction generalizes the Jacobi matrices of the recurrence relations for orthogonal polynomials.
