Consequences of the Darboux transformations for the finite-difference Schrodinger equations and three-term recurrence relations for orthogonal polynomials are considered …

We consider asymptotics of Christoffel functions for measures ν with compact support on the real line. It is shown that under some natural conditions n times the n th Christoffel function …
We obtain explicit formulas for the entries of the inverse of a nonsingular and irreducible tridiagonal k− Toeplitz matrix A. The proof is based on results from the theory of orthogonal …

A recent approach of DS Lubinsky yields universality in random matrix theory and fine zero spacing of orthogonal polynomials under very mild hypothesis on the weight function …

We begin the systematic study of the spectral theory of periodic Jacobi matrices on trees including a formal definition. The most significant result that appears here for the first time is …
We consider Chebyshev polynomials, T_n (z) T n (z), for infinite, compact sets e ⊂ R e⊂ R (that is, the monic polynomials minimizing the\sup sup-norm,|| T_n|| _ e|| T n|| e, on ee). We …

We develop a numerical method for computing with orthogonal polynomials that are orthogonal on multiple, disjoint intervals for which analytical formulae are currently …
