MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
The speed of travelling waves for convective reaction-diffusion equations
Steffen HeinzeAbstract
Explicit upper and lower estimates for the speed of fronts for reaction-diffusion equation with a convective shear flow are derived. The enhancement of the speed is proportional to the amplitude of the convection and proportional to the square root of the amplitude of the reaction. Several asymptotic regimes will be considered, i.e. large Peclet numbers, rapidly oscillating convection, and small diffusivity.
