Topological Unconstrained QCD
Victor Pervushin
"Equivalent unconstrained systems" for QCD obtained by resolving the Gauss law are discussed. We show that the effects of hadronization, confinement, spontaneous chiral symmetry br…
Topological invariant variables in QCD
D. Blaschke, V. Pervushin, G. Roepke
We show that the class of functions of topologically nontrivial gauge transformations in QCD includes a zero-mode of the Gauss law constraint. The equivalent unconstrained system c…
Reparametrization-Invariant Path Integral in GR and "Big Bang" of Quantum Universe
M. Pawlowski, V. N. Pervushin
The reparametrization-invariant generating functional for the unitary and causal perturbation theory in general relativity in a finite space-time is obtained. The region of validit…
Time reparametrization-invariant dynamics of a relativistic string
B. M. Barbashov, V. N. Pervushin
The time-reparametrization-invariant dynamics of a relativistic string is studied in the Dirac generalized Hamiltonian theory by resolving the first class constraints. The reparame…
