Yg. Miao et Ys. Duan, AN ALTERNATIVE LORENTZ-TYPE SYMMETRY OF THE THEORY OF CHIRAL BOSONS WITH INTERACTIONS, Communications in Theoretical Physics, 20(1), 1993, pp. 125-128
We canonically quantize the extended theory of chiral bosons described
by the Floreanini-Jackiw Lagrangian to include an interaction potenti
al, and obtain that the commutation relations of interacting chiral bo
sons coincide with those of free ones. We then construct an alternativ
e Lorentz-type symmetry for this theory in terms of the basic commutat
ion relation.
