Backward difference formula: The energy technique for subdiffusion equation

Minghua Chen, Fan Yu, Zhi Zhou

Based on the equivalence of A-stability and G-stability, the energy technique of the six-step BDF method for the heat equation has been discussed in [Akrivis, Chen, Yu, Zhou, Math.…

Analysis of (shifted) piecewise quadratic polynomial collocation for nonlocal diffusion model

Minghua Chen, Jiankang Shi, Xiaobo Yin

The piecewise quadratic polynomial collocation is used to approximate the nonlocal model, which generally obtain the {\em nonsymmetric indefinite system} [Chen et al., IMA J. Numer…

The energy technique for the six-step BDF method

Georgios Akrivis, Minghua Chen, Fan Yu +1

In combination with the Grenander--Szegö theorem, we observe that a relaxed positivity condition on multipliers, milder than the basic %fundamental requirement of the Nevanlinna--O…
