Stryzhak P. Quantitative measures, sensitivity, and bifurcations of mixed-mode and chaotic regimes for bromate and oxygen oscillators

The phenomenon of the deterministic chaos for bromate and oxygen oscillators. The systematic search and quantitative analysis of mixed-mode and deterministic chaotic regimes in the Belousov-Zhabotinskii oscillating reaction and in oxygen systems; the finding of the quantitative characteristics for determination of sensitivity of the deterministic chaotic oscillating regimes and for description of influence of small perturbations on them. The investigations are performed in batch and flow reactors using potentialmetric, spectrophotometric methods, atomic absorption spectrometry, microphotography, numerical methods of the analysis. The phenomenon of the transient deterministic chaos is grounded theoretically and investigated experimentally. Quantitative dependencies and bifurcations of the mixed-mode and deterministic chaotic regimes caused by the changes of system parameters are found experimentally. The methods for determination of chemical microimpurities are proposed. Application area is nonlinear ph enomena and analytical chemistry.
