2-local derivation on the conformal Galilei algebra
Yufang Zhao, Yongsheng Cheng
2-local derivation is a generalized derivation for a Lie algebra, which plays an important role to the study of local properties of the structure of the Lie algebra. In this paper,…
2-local derivations on the twisted Heisenberg-Virasoro algebra
Yufang Zhao, Yongsheng Cheng
2-local derivation is a generalized derivation for a Lie algebra, which plays an important role to the study of local properties of the structure of the Lie algebra. In this paper,…
Local cocycle 3-Hom-Lie Bialgebras and 3-Lie Classical Hom-Yang-Baxter Equation
Mengping Wang, Linli Wu, Yongsheng Cheng
In this paper, we introduce 3-Hom-Lie bialgebras whose compatibility conditions between the multiplication and comultiplication are given by local cocycle conditions. We study a tw…
Quantum group structure of the q-deformed algebra $\WW_q$
Huanxia Fa, Junbo Li, Yongsheng Cheng
In this paper the q-deformed algebra $\WW_q$ is constructed, whose nontrivial quantum group structure is presented.
