Path integral quantization of relativistic spinless particle in an external electromagnetic field

الملخص EN

The Hamilton-Jacobi formalism of constrained systems is discussed.

The equations of motion for a singular systems are obtained as total differential equations in many variables.

The integrability conditions for the system lead us to obtain the canonical reduced phase-space coordinates without using any gauge fixing condition.

The path integral quantization of relativistic spinless particle in an external electromagnetic field is also discussed.
