A Note on Statistical Averages for Oscillating Tableaux
Oscillating tableaux are certain walks in Young’s lattice of partitions; they generalize standard Young tableaux. The shape of an oscillating tableau is the last partition it visits and the length of an oscillating tableau is the number of steps it takes. We define a new statistic for oscillating tableaux that we call weight: the weight of an oscillating tableau is the sum of the sizes of all t...
متن کاملTheory for Diffusion-Limited Oscillating Chemical Reactions
A kinetic description of lattice-gas automaton models for reaction-diffusion systems is presented. It provides corrections to the mean field rate equations in the diffusion-limited regime. When applied to the two-species Maginu model, the theory gives an excellent quantitative prediction of the effect of slow diffusion on the periodic oscillations of the average concentrations in a spatially ho...
متن کاملTutorial Review: Simulation of Oscillating Chemical Reactions Using Microsoft Excel Macros
Oscillating reactions are one of the most interesting topics in chemistry and analytical chemistry. Fluctuations in concentrations of one the reacting species (usually a reaction intermediate) create an oscillating chemical reaction. In oscillating systems, the reaction is far from thermodynamic equilibrium. In these systems, at least one autocatalytic step is required. Developing an instinctiv...
متن کاملThe Bray-liebhafsky and Briggs-rauscher Oscillating Reactions
The common points and differences between the Bray-Liebhafsky and BriggsRauscher reactions are discussed. The reactants of the non-catalyzed version of the Briggs-Rauscher reaction being the same as those of the Bray-Liebhafsky reaction plus a reducing organic compound, the mechanisms of these two systems must have several common points. The marked difference between the oscillating behaviours ...
متن کاملThe Number of Autocatalytic Reactions in Systems of Oscillating Reaction
Some mathematical models have been proposed to elucidate the mechanism by which an oscillating reaction is generated as a complex system. Brusselator and Oregonator do not only describe oscillating reaction systems but also reproduce multiple periodic oscillations, burst waves and drawing synchronization. All theoretical researches on these models did not give each differential equation with co...
