Braided tensor products and polynomial invariants for the quantum queer superalgebra
Zhihua Chang, Yongjie Wang
The classical invariant theory for the queer Lie superalgebra investigates its invariants in the supersymmetric algebra $$\mathcal{U}_{s,l}^{r,k}:=\mathrm{Sym}\lef…

Finite-dimensional subalgebras of the Virasoro algebra
Zhihua Chang
We determine all two-dimensional Lie subalgebras of the centreless Virasoro algebra and complete the characterization of all finite dimensional Lie subalgebras of the complex Viras…
