The basic tools for fractional differentiation and fractional integration are then developed . The Hilger time scale calculus is obtained as a particular case , by choosing = 1 . Many basic properties of the theory are proved .frTime scales , Conformable fractional derivative , Conformable fractional integral , Conformable fractional calculus on time scales , A Mean Value Theorem , Absolutely continuous functionÉchelle de temps , Dérivée fractionnaire conformable , Intégrale fractionnaire conformable , Calcul fractionnaire conformable sur l’échelle de temps , Théorème de la moyenne , Fonction absolument continueThesis
