On the l2 Stability of Crank-Nicolson Difference Scheme for Time Fractional Heat Equations

Serife R. Bayramoglu Erguner, Ibrahim Karatay,
Abstract :
In this work, the matrix stability of the finite difference scheme based on Crank Nicolson method, for solving time-fractional heat equations, is investigated. An iterative formula is presented for the coefficient matrices of the error equations. Upper bounds for l2− norms of the coefficient matrices are obtained by a new method based on matrix diagonalization. A detailed numerical analysis, including tables figures and error comparisons, are given to demonstrate the theoretical results.

 

Riemann-Liouville Fractional Derivative and Application to Model Chaotic Differential Equations

Kolade M. Owolabi,
Abstract :
In this work, stability analysis and numerical treatment of chaotic time-fractional differential equations are considered. The classical system of ordinary differential equations with initial conditions is generalized by replacing the first-order time derivative with the Riemann-Liouville fractional derivative of order a, for 0 < a ≤ 1. In the numerical experiments, we observed that analysis of pattern formation in time-fractional coupled differential equations at some parameter value is almost similar to a classical process. A range of chaotic systems with current and recurrent interests which have many applications in biology, physics and engineering are taken to address any points and queries that may naturally occur.

 

BOUNDARY VALUE PROBLEMS FOR FRACTIONAL DIFFERENTIAL EQUATIONS WITH INTEGRAL AND ANTI-PERIODIC CONDITIONS IN A BANACH SPACE

WAFAA BENHAMIDA, JOHN R. GRAEF,SAMIRA HAMANI,
Abstract :
The authors study the existence of solutions to a class of fractional differential equations with anti-periodic and integral boundary conditions involving the Caputo fractional derivative of order r ∈ (0, 1]. The proof is based on M¨onch’s fixed point theorem.

Elina L. Shishkina,
Abstract :
n this article a theory of fractional powers of a singular hyperbolic operator on arbitrary spaces is discussed. Fourier–Hankel transform, semigroup property, boundedness in proper functional spaces and other properties of the mixed Riesz fractional integral generated by Bessel operator are obtained.

 

On the generalized $(k,\rho)-$fractional derivative

D. S. Oliveira, E. Capelas de Oliveira,
Abstract :
We generalize a fractional derivative type, the so-called $(k,\rho)-$fractional derivative. From this generalization, we establish some properties involving this operator. As an application we also show that the Cauchy problem is equivalent to a Volterra integral equation of second kind. We discuss, from this problem, some particular cases.

 

Analytical solution of time-fractional Navier-Stoke equation by natural homotopy perturbation method

Shehu Maitama,
Abstract :
An analytical method called the natural homotopy perturbation method for solving time-fractional Navier-Stokes was proposed. The natural homotopy perturbation method is coupling of a well known technique, homotopy perturbation method (HPM) and the natural transform method (NTM). The proposed analytical method gives a series solutions which converges within few iterations. The efficiency and the high accuracy of the analytical method are clearly illustrated.

Ehsan Ziaei,
Abstract :
In this paper a novel strategy in finding an approximate solution for nonlinear fractional optimal control is proposed. The measure theory is used to find the solution. There are different definition for fractional derivative and integral, in this work new definition which is named conformable fractional calculus is used. Analytically convergence of the proposed method is proved, finally

George A. Anastassiou, Ioannis K. Argyros,
Abstract :
The novelty of this paper is the design of suitable algorithms for solving equations on Banach spaces. Some applications of the semi-local convergence are suggested including Banach space valued functions of fractional calculus, where all integrals are of Bochner-type.

 

New Analytical Solutions and Approximate Solution of The Conformable Space-Time Fractional Sharma-Tasso-Olver Equation

O. Tasbozan, Y. C¸ enesiz, A. Kurt, O. S. Iyiola,
Abstract :
The main purpose of this article is to find the exact and approximate solutions of conformable space-time fractional Sharma-Tasso-Olver equation using first integral method (FIM) and q-homotopy analysis method (q-HAM) respectively. The obtained exact and numerical solutions are compared with each other. Also, the numerical results obtained by q-HAM are compatible with the exact solutions obtained by FIM. Hence, it is clearly seen that these techniques are powerful and efficient in finding approximate and exact solutions for nonlinear conformable fractional PDEs.

 

Mathematical analysis and numerical simulation of chaotic noninteger order differential systems with Riemann-Liouville derivative

Owolabi Kolade Matthew,
Abstract :
Stability analysis and numerical treatment of chaotic fractional differential system in Riemann-Liouville sense are considered in this paper. Simulation results show that chaotic phenomena can only occur if the reaction or local dynamics of such system is coupled or nonlinear in nature. Illustrative examples that are still of current and recurring interest to economists, engineers, mathematicians and physicists are chosen, to describe the points and queries that may arise.
