Resumen de The support of the associated measure to the Cowen's tridiagonal matrix

Dolores Barrios Rolanía , Emilio Torrano Fernández, Venancio Tomeo Perucha

• In this paper we consider a class of three-term recurrence relations, whose associated tridiagonal matrices are subnormal operators. In this cases, there are measures associated to the polynomials given by such relations. We study the support of these measures.
