Modelling through nonlinear flux-limited spreading


Reaction-diffusion equations are nowadays a basic tool in the modelling of populations whose dynamics is basically ruled by two processes: local reactions, in which the populations interact between themselves, and diffusion, which makes the populations spread out in the physical space.
In the ambient of embryonic morphogenesis [1], it has been proposed the adaptation of the classical linear diffusion mechanism (Fick’s Law) by considering flux-limited operators. The employment of limited diffusion ideas in biological ambients provokes new mathematical questions concerning pattern formation or even qualitative behavior. This talk is devoted to present recent advances in the analysis of traveling waves to some flux-limited reaction-diffusion models where the classical traveling wave profiles will coexist with discontinuous waves spreading through the medium with finite speed [2, 3].

The Catalan Mathematical Society invites participants to this first congress of a biannual series focusing on current research topics across several areas of Mathematics.

Plenary talks and thematic sessions have been selected by the Scientific Committee of the SCM. Special thanks are due to the organisers of the thematic sessions and to the local mathematical community as a whole for their support to this congress.
