Περίληψη: The paper settles the problem of the consistency of the existence of a single universal graph between a strong limit singular and its power. Assuming that in a model of \mathbf {GCH} \kappa is supercompact and the cardinals \theta < \kappa, \lambda > \kappa are regular, as an application of a more general method, we obtain a forcing extension in which cf(\kappa) = \theta, the Singular Cardinal Hypothesis fails at \kappa and there exists a universal graph at cardinality \lambda \in (\kappa,2^\kappa).
