General criteria for the stability of uniaxially ordered states of Incommensurate-Commensurate Systems

Abstract
Reconsidering the variational procedure for uniaxial systems modeled by continuous free energy functionals, we derive new general conditions for thermodynamic extrema. The utility of these conditions is briefly illustrated on the models for the classes I and II of incommensurate-commensurate systems.
