Abstract

In this paper, we characterize the boundedness and the compactness of weighted composition operators acting on a de Branges-Rovnyak space H(b)\mathcal H(b), where the symbol bb is a rational function in the unit ball of HH^\infty that is not a finite Blaschke product. Our results extend those of [2] by exploiting a close relationship between weighted composition operators on H(b)\mathcal H(b) and their counterparts on the Hardy space H2H^2.
