Regularity Analysis and High-Order Time Stepping Scheme for Quasilinear Subdiffusion

Bangti Jin, Qimeng Quan, Barbara Wohlmuth +1

In this work, we investigate a quasilinear subdiffusion model which involves a fractional derivative of order $\hat{I}\pm \in (0,1)$ in time and a nonlinear diffusion coefficient. First, us…
