This text takes advantage of recent developments in the theory of path integration to provide an improved treatment of quantization of systems that either have no constraints or involve constraints with demonstratively improved procedures.

A major paradigm shift in how the art of functional integration is practiced Will prove valuable to a broad audience of graduate students and researchers in physics, chemistry, mathematical physics, and applied mathematics Offers insight into contemporary research topics that cannot be found elsewhere in the textbook literature Includes exercises in most chapters Includes supplementary material: sn.pub/extras
