On the regularization scheme and gauge choice ambiguities in topologically massive gauge theories
J. Gegelia, A. Khelashvili, N. Kiknadze
It is demonstrated that in the (2+1)-dimensional topologically massive gauge theories an agreement of the Pauli-Villars regularization scheme with the other schemes can be achieved…
Practical scheme of reduction to gauge invariant variables
G. Chechelashvili, G. Jorjadze, N. Kiknadze
For systems with first class constraints the reduction scheme to the gauge invariant variables is considered. The method is based on the analysis of restricted 1-forms in gauge inv…
On Admissible Gauges for Constrained Systems
S. A. Gogilidze, A. M. Khvedelidze, V. N. Pervushin
The {\it {gauge - fixing} } and {\it gaugeless } methods for reducing the phase space in the generalized Hamiltonian dynamics are compared with the aim to define the class of admis…
On Abelianization of First Class Constraints
S. A. Gogilidze, A. M. Khvedelidze, V. N. Pervushin
The systematic method for the conversion of first class constraints to the equivalent set of Abelian one based on the Dirac equivalence transformation is developed. The representat…
