New universality classes for generic higher character Lifshitz points
  We describe new universality classes associated to generic higher character Lifshitz critical behaviors for systems with arbitrary short range competing interactions. New renormalization-group arguments are proposed for anisotropic and isotropic systems. The usual $m$-axial Lifshitz universality classes are obtained as a simple limit of this arbitrary competing critical behavior.
