En el presente trabajo se estudia un sistema acoplado que consiste en ecuaciones de Langevin de orden fraccional $ \psi $ -Hilfer complementadas con condiciones de contorno integral no locales. Los resultados de existencia y unicidad se obtienen mediante el uso de teoremas estándar de punto fijo. Los resultados obtenidos se ilustran bien mediante ejemplos numéricos.
Dans le présent travail, un système couplé composé d'équations de Langevin d'ordre fractionnaire $ \psi $ -Hilfer complétées par des conditions aux limites intégrales non locales est étudié. Les résultats d'existence et d'unicité sont obtenus en utilisant des théorèmes standard à virgule fixe. Les résultats obtenus sont bien illustrés par des exemples numériques.
In the present work a coupled system consisting by $ \psi $-Hilfer fractional order Langevin equations supplemented with nonlocal integral boundary conditions is studied. Existence and uniqueness results are obtained by using standard fixed point theorems. The obtained results are well illustrated by numerical examples.
