A numerical approach for solving a class of variable-order fractional functional integral equations.

This paper proposes new discretization techniques to estimate variable-order fractional integral operators based on the piecewise integro quadratic spline interpolation. The proposed methods are modified to solve a class of variable-order fractional functional integral equations. Moreover, we investigate the performance of the proposed methods by solving the variable-order fractional pantograph and Emden-Fowler functional integral equations. [ABSTRACT FROM AUTHOR]
