Extended Axial Model
R. Amorim, J. Barcelos-Neto
We study an extension of the axial model where local gauge symmetries are taken into account. The anomaly of the axial current is calculated by the Fujikawa formalism and the model…
A Note on Abelian Conversion of Constraints
Ricardo Amorim, Ashok Das
We show that for a system containing a set of general second class constraints which are linear in the phase space variables, the Abelian conversion can be obtained in a closed for…
BFT Quantization of Chiral-Boson Theories
R. Amorim, J. Barcelos-Neto
We use the method due to Batalin, Fradkin and Tyutin (BFT) for the quantization of chiral boson theories. We consider the Floreanini-Jackiw (FJ) formulation as well as others with…
The question of anomalies in the Chern-Simons theory coupled to matter fields
R. Amorim, J. Barcelos-Neto
We study the Chern-Simons theory coupled to matter field by means of an effective Lagrangian obtained from the Batalin-Fradkin-Vilkovisky formalism. We show that there is no rotati…
