Spin Norm and Lambda Norm
Chengyu Du, Chao-ping Dong
Given a -type , it is known that its spin norm (due to first-named author) is lower bounded by its lambda norm (due to Vogan). That is, $\|π\|_{\rm spin}\geq \|π\|_{\rm lambd…

3-Lie bialgebras and 3-Lie classical Yang-Baxter equations in low dimensions
Chengyu Du, Chengming Bai, Li Guo
In this paper, we give some low-dimensional examples of local cocycle 3-Lie bialgebras and double construction 3-Lie bialgebras which were introduced in the study of the classical…
