A New $L 2 - 1_{I ¨} $ -Interior Penalty Method for Variable-Order Time-Fractional Subdiffusion Interface Problem with Curved Interface

Hongying Huang, Chanchan Hao, Changmu Yu +1

This paper treats variable-order time-fractional subdiffusion with discontinuous coefficients across a curved interface using $L 2 - 1_{I ¨} $ time stepping on graded meshes and a sym…

Determining superconvergence points for $L 2 - 1_{I ¨} $ 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_{I ¨} $ temporal discretization with finite element spatial approximation. In existing works,…
