    "abstract": "Master equations describe the quantum dynamics of open systems interacting\nwith an environment. They play an increasingly important role in understanding\nthe emergence of semiclassical behavior and the generation of entropy, both\nbeing related to quantum decoherence. Presently we derive the exact master\nequation for a homogeneous scalar Higgs or inflaton like field coupled to an\nenvironment field represented by an infinite set of harmonic oscillators. Our\naim is to demonstrate a derivation directly from the path integral\nrepresentation of the density matrix propagator. Applications and\ngeneralizations of this result are discussed.",
