NIETO-VILLAR, J.M.; IZQUIERDO-KULICH, E.; QUINTANA, R.  and  RIEUMONT, J.. Una aproximación del criterio evolutivo de prigogine a sistemas químicos. Rev. mex. fis. [online]. 2013, vol.59, n.6, pp.527-529. ISSN 0035-001X.

Prigogine's evolution criterion is illustrated non-linear state nonlinear state in chemical reaction systems. It was proved that how at least in chemical reactions; the entropy production per unit time accords to the control parameters is in fact a Lyapunov function. This is indeed an evolution criterion in the nonlinear region and also the global stability is properly assured. Finally, it was shown that for fixed values of the control parameters, the system corresponding dynamical state exhibits a higher value of the entropy production per unit time, which can be considered in fact, an extension of the non-variational principle of maximum entropy.
