Possible Stabilization Mechanism with Bulk and Branes SO(N) Yang-Mills   for Closed Universes
  Widrawn: The solutions presented in this work are not compatible with the equation of motion for g_{00}, which we did not properly verify. In the framework of this work, the only bulk solutions compatible with periodicity of the fifth dimension are constant fields. Also for a scalar field only constant solutions are obtained.
