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 linear constraints.

We reconsider the CP 1 model with the Hopf term by using the BatalinFradkin-Tyutin (BFT) scheme, which is an improved version of the Dirac quantization method. We also perform a semi-classical quantization of the topological charge Q sector by exploiting the collective coordinates to explicitly show the fractional spin statistics.

We quantize the self-dual massive theory by using the Batalin-Tyutin Hamiltonian method, which systematically embeds second class constraint system into first class one in the extended phase space by introducing the new fields. Through this analysis we obtain simultaneously the Stückelberg scalar term related to the explicit gaugebreaking effect and the new type of Wess-Zumino action related to...

By using the Hamilton–Jacobi [HJ] framework, higher-order Maxwell–Chern–Simons theory is analyzed. The complete set of HJ Hamiltonians and a generalized differential are reported, from which all symmetries identified. In addition, we our study by performing Gitman–Lyakhovich–Tyutin [GLT] framework compare results both formalisms.
