On open string in generic background
Liu Zhao, Wenli He
A set of consistent Poisson brackets for an open string in generic spacetime background and NS-NS -field is constructed. Upon quantization, this set of Poisson brackets lead to…
Infinite Hopf Families of Algebras and Yang-Baxter Relations
Niall MacKay, Liu Zhao
A Yang-Baxter relation-based formalism for generalized quantum affine algebras with the structure of an infinite Hopf family of (super-) algebras is proposed. The structure of the…
On two-parameter deformations of
Liu Zhao, Xiang-Mao Ding
An elliptic two-parameter deformation of the (universal enveloping superalgebra of) affine Lie superalgebra is proposed in terms of free boson realization. This de…
Quantum currents in the Coset Space SU(2)/U(1)
Xiang-Mao Ding, Bo-Yu Hou, Liu Zhao
We propose a rational quantum deformed nonlocal currents in the homogenous space , and in terms of it and a free boson field a representation for the Drinfeld current…
Generalized quantum current algebras
Liu Zhao
Two general families of new quantum deformed current algebras are proposed and identified both as infinite Hopf family of algebras, a structure which enable one to define ``tensor…
Nonelectromagnetic duality in twisted N=4 model
Pei Wang, Liu Zhao
In this paper we discuss the possible existing correlation functions in the N=4 topological model. Due to the distinguished feature that no anomaly exists in N=4 supersymmetric the…
