The catastrophe theory describing sudden abrupt changes of a system has well-developed methods of investigation of the critical regimes. An application of these methods to the minimal supersymmetric standard model finite-temperature Higgs potential gives some interesting results. The nonlinear axes-conserving transformations are derived, which reduce the finite-temperature Higgs potential to canonical forms of the catastrophe theory.
