Correction of high-order approximation for subdiffusion
Jiankang Shi, Minghua Chen, Yubin Yan +1
The subdiffusion equations with a Caputo fractional derivative of order arise in a wide variety of practical problems, which is describing the transport processes, in…
Variable step-size BDF3 method for Allen-Cahn equation
Minghua Chen, Fan Yu, Qingdong Zhang +1
In this work, we analyze the three-step backward differentiation formula (BDF3) method for solving the Allen-Cahn equation on variable grids. For BDF2 method, the discrete orthogon…
Weighted and shifted BDF2 methods on variable grids
Minghua Chen, Fan Yu, Qingdong Zhang
Variable steps implicit-explicit multistep methods for PDEs have been presented in [17], where the zero-stability is studied for ODEs; however, the stability analysis still remains…
BDF SAV schemes for time-fractional Allen-Cahn dissipative systems
Fan Yu, Minghua Chen
Recently, the error analysis of BDF SAV (scalar auxiliary variable) schemes are given in \cite{Huangg:20} for the classical Allen-Cahn equation. Howev…
DeepOPF-V: Solving AC-OPF Problems Efficiently
Wanjun Huang, Xiang Pan, Minghua Chen +1
AC optimal power flow (AC-OPF) problems need to be solved more frequently in the future to maintain stable and economic power system operation. To tackle this challenge, a deep neu…
