in this paper, we prove the existence of the solution for boundary value prob-lem(bvp) of fractional di erential equations of order q 2 (2; 3]. the kras-noselskii's xed point theorem is applied to establish the results. in addition,we give an detailed example to demonstrate the main result.

in this article, we survey the asymptotic stability analysis of fractional differential systems with the prabhakar fractional derivatives. we present the stability regions for these types of fractional di fferential systems. a brief comparison with the stability aspects of fractional differential systems in the sense of riemann-liouville fractional derivatives is also given.

in this work, we proposed an ef ective method based on cubic and pantic b-spline scaling functions to solve partial di fferential equations of frac- tional order. our method is based on dual functions of b-spline scaling func- tions. we derived the operational matrix of fractional integration of cubic and pantic b-spline scaling functions and used them to transform the mentioned equations to a ...

reduced diff erental transform method (rdtm), which isone of the useful and eff ective numerical method, is applied to solve nonlinear time-dependent foam drainage equation (fde) with di fferent initial conditions. we compare our method with the famous adomian decomposition and laplace decomposition methods. the obtained resultsdemonstrated that rdtm is a powerful tool for solving nonlinear par...

in this work, we conduct a comparative study among the combine laplace transform and modi ed adomian decomposition method (lmadm) and two traditional methods for an analytic and approximate treatment of special type of nonlinear volterra integro-diff erential equations of the second kind. the nonlinear part of integro-di fferential is approximated by adomian polynomials, and the equation is red...

We derive a fractional reaction–di usion equation from a continuous-time random walk model with temporal memory and sources. The equation provides a general model for reaction–di usion phenomena with anomalous di usion such as occurs in spatially inhomogeneous environments. As a rst investigation of this equation we consider the special case of single species fractional reaction–di usion in one...

The TIB3-256 hashing algorithm [3] is a first round candidate in the SHA-3 competition [2]. Properties of the message expansion and the PHTX function are observed, and then exploited to create new high-probability differential paths through the compression function. Examples conforming to the differential paths are presented. Only one of these differential paths can be applied to the tweaked ve...

in this work, we have applied elzaki transform and he's homotopy perturbation method to solvepartial di erential equation (pdes) with time-fractional derivative. with help he's homotopy per-turbation, we can handle the nonlinear terms. further, we have applied this suggested he's homotopyperturbation method in order to reformulate initial value problem. some illustrative examples...
