RT info:eu-repo/semantics/article T1 Recurrent equation with sign and Fredholm alternative A1 Campos, Juan A1 Obaya, Rafael A1 Tarallo, Massimo AB We prove that a Fredholm--type Alternative holds for recurrent equations with sign, extending a previous result by Cieutat and Haraux in [3]. Moreover, we show that this can be seen a particular case of [1] and we provide a solution to an interesting question raised by Hale in [6]. Finally we characterize the existence of exponential dichotomies also in the nonrecurrent case.
