Self-Orthogonal Twisted Generalized Reed-Solomon Codes and Their Application to Quantum Error-Correcting Codes
Yanxin Chen, Yanli Wang, Tongjiang Yan
In this paper, two classes of twisted generalized Reed-Solomon (TGRS) codes with multi-twists are studied. Firstly, some sufficient and necessary conditions for these codes to be s…

MDS and NMDS Codes from the Extended Twisted Generalized Reed-Solomon Codes
Yanli Wang, Yanxin Chen, Tongjiang Yan
This paper contributes to maximum distance separable (MDS) and near MDS (NMDS) properties of the extended generalized twisted Reed-Solomon (TGRS) codes. Firstly, a family of extend…

Solving Vlasov-Poisson system with an adaptive Hermite spectral method
Sihong Shao, Yanli Wang, Jie Wu
We propose an adaptive Hermite spectral method for the Vlasov-Poisson system based on a recently developed frequency indicator that measures the contribution of the high-order expa…
