Differential operator realizations of superalgebras and free field representations of corresponding current algebras
Wen-Li Yang, Yao-Zhong Zhang, Samuel Kault
Based on the particular orderings introduced for the positive roots of finite dimensional basic Lie superalgebras, we construct the explicit differential operator representations o…
On explicit free field realizations of current algebras
Wen-Li Yang, Yao-Zhong Zhang
We construct the explicit free field representations of the current algebras , and for a generic positive integer and an arbitrary level .…
Free field realization of current superalgebra
Wen-Li Yang, Yao-Zhong Zhang, Xin Liu
We construct the free field representation of the affine currents, energy-momentum tensor and screening currents of the first kind of the current superalgebra uniformly…
Free field realization of the current algebra
Wen-Li Yang, Yao-Zhong Zhang
The current algebra for a {\it generic} positive integer at general level is investigated. Its free field representation and corresponding energy-momentum tens…
Bethe Ansatz Solutions to Quasi Exactly Solvable Difference Equations
Ryu Sasaki, Wen-Li Yang, Yao-Zhong Zhang
Bethe ansatz formulation is presented for several explicit examples of quasi exactly solvable difference equations of one degree of freedom which are introduced recently by one of…
On Pointed Hopf Algebras with Weyl Groups of exceptional type
Shouchuan Zhang, Yao-Zhong Zhang, Peng Wang +2
All -1-type pointed Hopf algebras and central quantum linear spaces with Weyl groups of exceptional type are found. It is proved that every non -1-type pointed Hopf algebra with re…
Classification of Quiver Hopf Algebras and Pointed Hopf Algebras of Type One
Shouchuan Zhang, Hui-Xiang Chen, Yao-Zhong Zhang
The quiver Hopf algebras are classified by means of ramification systems with irreducible representations. This leads to the classification of Nichols algebras over group algebras…
