A Numerical Study of Nonlinear Fractional Order Partial Integro-Differential Equation with a Weakly Singular Kernel

Abstract: Fractional differential equations can present the physical pathways with the storage and inherited properties due to the memory factor of fractional order. The purpose of this work is to interpret the collocation approach for tackling the fractional partial integro-differential equation (FPIDE) by employing the extended cubic B-spline (ECBS). To determine the time approximation, we utilize the Caputo approach. The stability and convergence analysis have also been analyzed. The efficiency and reliability of the… Show more

“…To discretize the time and space derivatives, the Caputo fractional derivative (CFD) approximation and new ExCuBS approximation for second derivative are applied, respectively. The non-linear FPIDE [30] 0 0 with initial condition (IC): and the boundary conditions (BCs): where 0 1 are fractional parameters, 0 are any constants and , are given functions. The represents the CFD with Euler's Gamma function Γ, which is defined as: Non-integer order derivatives and operators in terms of integral are more appropriate than ordinary derivatives and integration at various phases of real systems because they give a more detailed explanation of the structural and genetic characteristics of a number of dynamical and physical processes.…”
