As the generalized Landau expression, the star catastrophe potential wasinvestigated. The potential contains four control variables and a behavior varia ble,which are related to four field variables and one order parameter in physicalsystems by diffeomorphisms. The phase diagram, structure of critical spaces andcoexistence spaces, in four-dimensional space were obtained. New types of sin-gularity named critical coexistence space appear in this potential, which has beenintroduced by Griffiths as critical end point. In a certain range of the controlvariables, the triple hysteresis loop was found for this potential with one orderparameter.
