Exact solution of a class of fractional integro‐differential equations with the weakly singular kernel based on a new fractional reproducing kernel space

Abstract

In this paper, we construct a new fractional weighted reproducing kernel space, which is the minimum space containing the exact solution. The closed form of the reproducing kernel is obtained. Using this fractional reproducing kernel space, a class of fractional integro-differential equations with a weakly singular kernel is solved. The error estimation is given. The final numerical experiments demonstrate the correctness of the theory and the effectiveness of the method.KEYWORDS fractional integro-differential equation, fractional reproducing kernel space, weakly singular kernel 1 0 k(x, )u( )d + g(x), m − 1 < ≤ m, u (k) (0) = 0, k = 0, 1, · · · , m − 1,Math Meth Appl Sci. 2018;41:3841-3855.wileyonlinelibrary.com/journal/mma

A new stable collocation method for solving a class of nonlinear fractional delay differential equations

A High-Order Numerical Method for a Nonlinear System of Second-Order Boundary Value Problems

“…Here we extend QNM to solve nonlinear systems (1). Many improved versions of RKM have been developed to solve linear second-order BVPs [14][15][16][17][18][19][20][21]. However, the high-order RKM has been seldom discussed.…”
