Abstract
A theory is presented for the successive sixfold Fourier components, , in the bondorientational order in the neighborhood of a phase transition. Near the transition we predict that with where depends weakly on . General arguments are presented for the topology of the phase diagram in the vicinity of the smectic "liquid-hexatic-crystal" triple point which lead to the existence of a tricritical point on the line.
