  We propose a model for charge density waves in ring shaped crystals, which
depicts frustration between intra- and inter-chain couplings coming from
cylindrical bending. It is then mapped to a three dimensional uniformly
frustrated XY model with one dimensional anisotropy in connectivity. The
nonequilibrium relaxation dynamics is investigated by Monte Carlo simulations
to find a phase transition which is quite different from that of usual whisker
crystal. We also find that the low temperature state is a three dimensional
phase vortex lattice with a two dimensional phase coherence in a cylindrical
shell and the system shows power law relaxation in the ordered phase.
