Stability of ratio asymptotics of orthogonal polynomials under some class of measure perturbations
We consider a finite mass points perturbation of a measure supported by a system of curves and arcs in the complex plane. We study the corresponding perturbation of the ratio asymptotics of the associated monic orthogonal polynomials. Our main result gives a description of the perturbations for whic...

| Tartalmi kivonat: | We consider a finite mass points perturbation of a measure supported by a system of curves and arcs in the complex plane. We study the corresponding perturbation of the ratio asymptotics of the associated monic orthogonal polynomials. Our main result gives a description of the perturbations for which the ratio asymptotics is not changed. |
