The technique used to show the existence of random mild solutions is a generalization of the original Darbo fixed point theorem for Frechet spaces combined with the notion of measure of noncompactness, and we prove that our problems are controllable.eninfo:eu-repo/semantics/closedAccessFunctional Differential EquationRandom Mild SolutionCosine And Sine FamiliesFrechet SpaceControllabilityArticle202Q2Q2WOS:000923649400013
