Group Transformations of Semiclassical Gauge Systems
Oleg Shvedov
Semiclassical systems being symmetric under Lie group are studied. A state of a semiclassical system may be viewed as a set (X,f) of a classical state X and a quantum state f in th…
On Correspondence of BRST-BFV, Dirac and Refined Algebraic Quantizations of Constrained Systems
Oleg Yu. Shvedov
Correspondence between BRST-BFV, Dirac and refined algebraic (group averaging, projection operator) approaches to quantize constrained systems is analyzed. For the closed-algebra c…
Semiclassical Mechanics of Constrained Systems
Oleg Shvedov
Semiclassical mechanics of systems with first-class constraints is developed. Starting from the quantum theory, one investigates such objects as semiclassical states and observable…
Semiclassical Symmetries
Oleg Yu. Shvedov
Essential properties of semiclassical approximation for quantum mechanics are viewed as axioms of an abstract semiclassical mechanics. Its symmetry properties are discussed. Semicl…
Renormalization of Poincare Transformations in Hamiltonian Semiclassical Field Theory
Oleg Yu. Shvedov
Semiclassical Hamiltonian field theory is investigated from the axiomatic point of view. A notion of a semiclassical state is introduced. An "elementary" semiclassical state is spe…
BRST-BFV, Dirac and Projection Operator Quantizations: Correspondence of States
Oleg Yu. Shvedov
The correspondence between BRST-BFV, Dirac and projection operator approaches to quantize constrained systems is analyzed. It is shown that the component of the BFV wave function w…
