A New $L2-1_{\ddot{I}}ƒ$-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 $L2-1_{\ddot{I}}ƒ$ time stepping on graded meshes and a sym…
