What is SU(2) Coherent State Path Integrals about?

This document presents a basic formulation of SU(2) coherent state path integrals labeled by a full set of Euler angles, using arbitrary fiducial vectors rather than the conventional choices. The coherent states are defined on a 3-sphere and generally have no classical analogues. An overcompleteness relation is derived for the states. Using this, the time evolution of general systems is obtained via a path integral representation, with the resulting Lagrangian containing a monopole-type term and additional
