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…
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…
Refined Algebraic Quantization of Constrained Systems with Structure Functions
Oleg Yu. Shvedov
The method of refined algebraic quantization of constrained systems which is based on modification of the inner product of the theory rather than on imposing constraints on the phy…
Poincare Invariance of Hamiltonian Semiclassical Field Theory
Oleg 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…
