Query: An Introduction to Coordinate-free Quantization and its Application to
  Constrained Systems   Canonical quantization entails using Cartesian coordinates, and Cartesian
coordinates exist only in flat spaces. This situation can either be questioned
or accepted. In this paper we offer a brief and introductory overview of how a
flat phase space metric can be incorporated into a covariant, coordinate-free
quantization procedure involving a continuous-time (Wiener measure)
regularization of traditional phase space path integrals. Additionally we show
how such procedures can be extended to incorporate systems with constraints and
illustrate that extension for special systems.
