En este artículo presentamos una condición sufiente y una condición necesaria para el Problema Inverso de Autovalores para Matrices Simétricas no Negativas. Esta condición es independiente de los criterios de realizabilidad existentes. Este criterio es recursivo, es decir determina si una lista Λ= {λ1, …, λn, λn+1} es realizable por una matriz simétrica no negativa, si la lista μ = {μ1, ..., μn} asociada a Λ es realizable. Este resultado es fácil de programar y mejora algunos criterios existentes. MSC2010: 15A29, 15A18, 15B10, 15A57. In this paper we present a sufficient ondition and a necessary condition for Symmetri Nonnegative Inverse Eigenvalue Problem. This condition is independent of the existing realizability criteria.
