Abstract
A criterion to locate tricritical points in phase diagrams is proposed. The criterion is formulated in the framework of elementary catastrophe theory and encompasses all the existing criteria in that it applies to systems described by a generally nonsymmetric free energy which can depend on one or more order parameters. We show that tricritical points are necessarily given by free energies which are not 4-determined. An application to smectic-C liquid crystals is briefly discussed.
