Phase-space transition states stationary points

Far from the point of thermodynamic equifrbrium, the evolution of a system toward its stationary state is governed by the particular behavior of function P in the phase space of thermodynamic forces Xj and fluxes Jj (i,j = 1,. .., m). In the point describing the system stationary state in this phase space, the final value of function P is independent of the starting conditions and of the way of arriving at this point. This implies equiva lence of the transition to the final stationary state of the system and of the movement normally to equipotential surfaces of function P ...
