Numerical approximations for a hyperbolic integrodifferential equation with a non-positive variable-sign kernel and nonlinear-nonlocal damping

Wenlin Qiu, Xiangcheng Zheng, Kassem Mustapha

This work considers the Galerkin approximation and analysis for a hyperbolic integrodifferential equation, where the non-positive variable-sign kernel and nonlinear-nonlocal dampin…

An $α$ -robust and second-order accurate scheme for a subdiffusion equation

Kassem Mustapha, William McLean, Josef Dick

We investigate a second-order accurate time-stepping scheme for solving a time-fractional diffusion equation with a Caputo derivative of order~ $α \in (0, 1)$ . The basic idea of our s…
