When set up appropriately, autocatalytic chemical reactions (taking the usual meaning of the term) frequently give rise to a "bistability" (in particular bistationarity), and chemical hysteresis as its corollary. Since these reactions are relatively well documented elsewhere, it does not appear necessary to list them all there, particularly since they are quite numerous. Conversely, oscillatory chemical reactions in homogeneous chemical media are rather rarer and, apart from two exceptions, have recently been discovered. Since there is no satisfactory criterion permitting the classification of chemical oscillators at present, we can do little more than record them in a somewhat arbitrary order [Pg.442]

In order to form a bridge between the laboratory (chemical) experiments and the theoretical (mathematical) models we refer to Table I. In a traditional approach, experimental chemists are concerned with Column I of Table I. As this table implies there are various types of research areas thus research interests. Chemists interested in the characteristics of reactants and products resemble mathematicians who are interested in characteristics of variables, e.g. number theorists, real and complex variables theorists, etc. Chemists who. are interested in reaction mechanism thus in chemical kinetics may be compared to mathematicians interested in dynamics. Finally, chemists interested in findings resulting from the study of reactions are like mathematicians interested in critical solutions and their classifications. In chemical reactions, the equilibrium state which corresponds to the stable steady states is the expected result. However, it is recently that all interesting solutions both stationary and oscillatory, have been recognized as worthwhile to consider. [Pg.3]
