Remarks on the Second Homology Groups of Queer Lie Superalgebras

Yongjie Wang, Zhihua Chang

The aim of this note is to completely determine the second homology group of the special queer Lie superalgebra $sq_{n} (R)$ coordinatized by a unital associative superalge…

Central extensions of generalized orthosymplectic Lie superalgebras

Zhihua Chang, Yongjie Wang

The key ingredient of this paper is the universal central extension of the generalized orthosymplectic Lie superalgebra $osp_{m ∣2 n} (R,^{-})$ coordinatized by a unital as…

Second homology of generalized periplectic Lie superalgebras

Zhihua Chang, Jin Cheng, Yongjie Wang

Let $(R,^{-})$ be an arbitrary unital associative superalgebra with superinvolution over a commutative ring $k$ with $2$ invertible. The second homology of the generalized peri…

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…

On twisted large N=4 conformal superalgebras

Zhihua Chang, Arturo Pianzola

We explicitly compute the automorphism group of the large N = 4 conformal superalgebra and classify the twisted loop conformal superalgebras based on the large N = 4 conformal supe…

The automorphism group functor of the N=4 Lie conformal superalgebra

Zhihua Chang

In this paper, we study the structure and representability of the automorphism group functor of the N=4 Lie conformal superalgebra over an algebraically closed field k of character…
