Reconstruction of a potential parameter in subdiffusion via a Kohn--Vogelius type functional: Theory and computation

Hamza Kahlaoui, Mourad Hrizi, Abdessamad Oulmelk +3

This work considers the reconstruction of a space-dependent potential from boundary observations in subdiffusion by a stable and robust recovery method. Specifically, we develop an…

Determining superconvergence points for $L 2 - 1_{σ}$ scheme of variable-exponent subdiffusion and error estimate

Hongying Huang, Huili Zhang, Xiangcheng Zheng

We develop a numerical scheme for subdiffusion of variable exponent by combining the $L 2 - 1_{σ}$ temporal discretization with finite element spatial approximation. In existing works,…
