Abstract
We propose a new canonical form of the fluctuational Hamiltonian which takes into account the fact that in the vicinity of the critical point there are two fluctuating fields. They are the field of the number density and the entropy. The proposed canonical form is based on the D5 catastrophe. In contrast to the standard approach of Landau-Ginzburg Hamiltonian which is based on A3 catastrophe the canonical form proposed for the fluctuational Hamiltonian naturally includes the asymmetric coupling between the fields.
