On the variety of traveling fronts in one-variable multistable reaction-diffusion systems

J Phys Chem A. 2006 Jun 29;110(25):7882-7. doi: 10.1021/jp062292h.

Abstract

The still-open problem of the variety of asymptotic solutions to one-variable, one-dimensional infinite multistable reaction-diffusion systems is solved. We show that in such systems, besides monotonic traveling fronts, nonmonotonic traveling fronts can exist for appropriate initial conditions. The dependence of numbers of various types of traveling fronts on the number of stable stationary states also is given. Examples of traveling fronts for the chemical model describing two enzymatic (catalytic) reactions inhibited by an excess of their reactant is presented.
