Forward and backward problems for coupled subdiffusion systems
Dian Feng, Yikan Liu, Shuai Lu
In this article, we investigate both forward and backward problems for coupled systems of time-fractional diffusion equations, encompassing scenarios of strong coupling. For the fo…

Global and local existence of solutions for nonlinear systems of time-fractional diffusion equations
Dian Feng, Masahiro Yamamoto
In this paper, we consider initial-boundary value problems for two-component nonlinear systems of time-fractional diffusion equations with the homogeneous Neumann boundary conditio…
