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…

W-symmetries on the Homogeneous Space G/U(1)^r
Xiang-Mao Ding, Pei Wang
A construction of -symmetries is given only in terms of the nonlocal fields (parafermions ${\ps}_{\al}$), which take values on the homogeneous space , where is a s…
