Canonical quantization of chiral bosons

Physical Review Letters, 1989
We perform the canonical quantization for a system of non-Abelian chiral bosons. We show that unlike in the Wess-Zumino-Witten model, the left- and right-handed current densities do not simultaneously span Kac-Moody algebras in the quantum theory. At the critical values of the coupling constants, only one Kac-Moody algebra results.

Canonical quantization of constrained systems

Physical Review A, 1990
The consideration of first-class constraints together with gauge conditions as a set of second-class constraints in a given system is shown to be incorrect when carrying out its canonical quantization.

Canonical quantization of singular theories

Soviet Physics Journal, 1983
We construct here a formal operator formulation of a singular theory. In tackling this problem we shall bear in mind that there are many physically equivalent classical theories which can describe a physical system. Hence one may believe that all the quantum theories corresponding to these classical theories must also be physically equivalent and that ...
