AbstractDue to its extraordinary modeling capabilities, the nonlocal fractional-order Laplacian has recently attracted increasing scientific and engineering attention in the past decade. However, the nonlocal operators bring up new challenges in discretization, computation and analysis for the associated PDEs. To cope with these difficulties, we present two efficient numerical methods, the radial basis functions and neural-network methods. For both methods, we discuss their convergence analysis. Some numerical examples are provided to demonstrate their efficiency and accuracy.
