In this lecture, a limited introduction of gauge invariance in phase-space isprovided, predicated on canonical transformations in quantum phase-space. Exactcharacteristic trajectories are also specified for the time-propagating Wignerphase-space distribution function: they are especially simple - indeed,classical - for the quantized simple harmonic oscillator. This serves as theunderpinning of the field theoretic Wigner functional formulation introduced.Scalar field theory is thus reformulated in terms of distributions in fieldphase-space.
