This paper studies the existence of solutions for a coupled system of nonlinear fractional integro-di ff erential equations involving Riemann-Liouville integrals with several continuous functions. New ...

In this paper, we study the existence and uniqueness of solutions for a nonlinear fractional boundary value problem. New results are established using a Banach contraction principle and Schaefer's fixed point ...

In this paper, we present new results for a coupled system of fractional dif- ferential equations. Applying Banach contraction principle and Schaefer fixed point theorem, new existence and uniqueness results are obtained. ...

New concepts on fractional probability theory are introduced and some inequalities for the fractional w􀀀weighted expectation and the fractional w􀀀weighted variance of continuous random variables are obtained. Other ...
