S. M. ALMekhlafi,
N. H. Sweilam,
A. N. Hassan,


Abstract
: 

In this article, a general model for Inuenza of two groups is presented as a fractional
order model. The fractional derivatives for this model which consist of eight dier
ential equations are dened in the sense of Caputo denition. To obtain an ecient
numerical method, the fraction order derivatives are approximated by the shifted Ja
cobi polynomials. The proposed scheme reduces the solution of the main problem
to the solution of a system of nonlinear algebraic equations. Comparative studies
between the proposed method and both the fourthorder RungeKutta method and
the generalized Euler method are done. 






On the local Mderivative


J. Vanterler da C. Sousa,
E. Capelas de Oliveira,


Abstract
: 

We introduce a new local derivative that generalizes the socalled alternative $"fractional"$ derivative recently proposed. We denote this new differential operator by $\mathscr{D}_{M}^{\alpha,\beta}(\cdot)$, where the parameter $\alpha$, associated with the order, is such that $0<\alpha<1$, $\beta>0$ and $M$ is used to denote that the function to be derived involves a MittagLeffler function with one parameter. This new derivative satisfies some properties of integerorder calculus, e.g. linearity, product rule, quotient rule, function composition and the chain rule. Besides as in the case of the Caputo derivative, the derivative of a constant is zero. Because MittagLeffler function is a natural generalization of the exponential function, we can extend some of the classical results, namely: Rolles theorem, the mean value theorem and its extension. We present the corresponding $M$integral from which, as a natural consequence, new results emerge which can be interpreted as applications. Specifically, we generalize the inversion property of the fundamental theorem of calculus and prove a theorem associated with the classical integration by parts. Finally, we present an application involving linear differential equations by means of local $M$derivative with some graphs.

Canavati Fractional Approximation by Maxproduct Operators


George A. Anastassiou,


Abstract
: 

Here we study the approximation of functions by sublinear positive operators with applications to a large variety of Max
Product operators under Canavati fractional differentiability. Our approach is based on our general fractional results about positive
sublinear operators. We derive Jackson type inequalities under simple initial conditions. So our way is quantitative by producing
inequalities with their right hand sides involving the modulus of continuity of Canavati fractional derivative of the function under
approximation.

A novel approach to fractional calculus: utilizing fractional integrals and derivatives of the Dirac delta function


Evan Camrud,


Abstract
: 

While the definition of a fractional integral may be codified by Riemann and Liouville, an agreedupon fractional derivative has eluded discovery for many years. This is likely a result of integral definitions including numerous constants of integration in their results. An elimination of constants of integration opens the door to an operator that reconciles all known fractional derivatives and shows surprising results in areas unobserved before, including the appearance of the Riemann Zeta function and fractional Laplace and Fourier Transforms. A new class of functions, known as Zero Functions and closely related to the Dirac delta function, are necessary for one to perform elementary operations of functions without using constants. The operator also allows for a generalization of the Volterra integral equation, and provides a method of solving for Riemanns ``complimentary function introduced during his research on fractional derivatives. 






Local Fractional Natural Homotopy Perturbation Method for Solving Partial Differential Equations with Local Fractional Derivative


Shehu Maitama,


Abstract
: 

A new analytical method called the Local Fractional Natural Homotopy Perturbation Method (LFNHPM) for solving partial differential equations with local fractional
derivative is introduced. The proposed analytical method is a combination of the homotopy perturbation method (HPM) and the natural transform (NTM). In this analytical method, the fractional derivative operators are computed in local fractional sense. Some applications are given to illustrate the simplicity, efficiency, and high accuracy of the Local Fractional Natural Homotopy Perturbation Method. 






A New Approach for Solving Fractional Optimal Control Problems Using Shifted Ultraspherical Polynomials


Hoda F. Ahmed,
Marina B. Melad,


Abstract
: 

Through this article, we introduce a numerical technique for solving one and two dimensional fractional optimal control problems (FOCPs). The proposed technique based on using the operational matrix (OM) of the Riemmaan– Liouville (RL) fractional integral of the shifted
Gegenbauer polynomials (SGPs) to transform the FOCP into an equivalent variational problem. By using the Gegenbauer Gauss quadrature method (GGQM) with the Rayleigh Ritz method (RRM) the resultant variational problem is reduced to a system of algebraic equations
(AEs) which is easily to solve. Illustrative problems included one and two dimensional FOCPs are provided to illustrate the powerful and validity of our method.

This paper deals with the initial value problem for the multiterm fractional differential equation. The fractional derivative is defined in the Caputo sense. Firstly the initial value problem is transformed into a equivalent Volterratype integral equation under appropriate assumptions.
