A Meshless Method for Numerical Solution of Fractional Differential Equations
In this paper, a technique generally known as meshless numerical scheme for solving fractional dierential equations isconsidered. We approximate the exact solution by use of Radial Basis Function(RBF) collocation method. This techniqueplays an important role to reduce a fractional dierential equation to a system of equations. The numerical results demonstrate the accuracy and ability of this me...

متن کاملUpper and Lower Solution Method for Fractional Boundary Value Problems on the Half-Line
where D 0 denotes the Riemann Liouville fractional derivative of order q, 1 < q < 2, η > 0, f : [0,∞) × R → R and e : [0,∞) → R are given functions satisfying some conditions. The problem (1.1)–(1.2) happens to be at resonance in the sense that the dimension of the kernel of the linear operator Lx = D 0+x is not less than one under boundary conditions (1.2). It should be noted that in recent ye...
متن کاملExact Solution for Nonlinear Local Fractional Partial Differential Equations
In this work, we extend the existing local fractional Sumudu decomposition method to solve the nonlinear local fractional partial differential equations. Then, we apply this new algorithm to resolve the nonlinear local fractional gas dynamics equation and nonlinear local fractional Klein-Gordon equation, so we get the desired non-differentiable exact solutions. The steps to solve the examples a...
متن کاملUsing operational matrix for numerical solution of fractional differential equations
In this article, we have discussed a new application of modification of hat functions on nonlinear multi-order fractional differential equations. The operational matrix of fractional integration is derived and used to transform the main equation to a system of algebraic equations. The method provides the solution in the form of a rapidly convergent series. Furthermore, error analysis of the pro...
