The Zeta Function Method and the Harmonic Oscillator Propagator
arXiv:physics/0508201 · doi:10.1119/1.1311784
Abstract
We show how the pre-exponential factor of the Feynman propagator for the harmonic oscillator can be computed by the generalized -function method. Besides, we establish a direct equivalence between this method and Schwinger's propertime method.
