There is a vast theory of the asymptotic behavior of orthogonal polynomials with respect to a measure onand its applications to Jacobi matrices. That theory has an obvious affine invariance and a very special role for. We extend aspects of this theory in the setting of rational functions with poles on, obtaining a formulation which allows multiple poles and proving an invariance with respect to-preserving Möbius transformations. We obtain a characterization of Stahl–Totik regularity of a GMP matrix in terms of its matrix elements; as an application, we give a proof of a conjecture of Simon–a Cesàro–Nevai property of regular Jacobi matrices on finite gap sets.
