Comment on Path Integral Derivation of Schr\"odinger Equation in Spaces   with Curvature and Torsion
  We present a derivation of the Schr\"odinger equation for a path integral of a point particle in a space with curvature and torsion which is considerably shorter and more elegant than what is commonly found in the literature.
