Abstract:
Scalar field systems containing higher derivatives are studied and quan-
tized by Hamiltonian path integral formalism. A new point to previous quantization
methods is that field functions and their time derivatives are considered as indepen-
dent canonical variables. Consequently, generating functional, explicit expressions of
propagators and Feynman diagrams in 3 theory are found.
