Abstract
We derive the first order canonical formulation of cosmological pertur bation theory in a Universe filled by a few scalar fields. This theory is quantized via a well-defined Hamiltonian path integral. The propag ator which describes the evolution of the initial (for instance, vacuu m) state, is calculated.
