Abstract:
In this paper we study the existence of one-dimensional and
multidimensional traveling wave solutions for general chemotaxis or
so-called Keller-Segel models without reproduction of the chemotactic
species. We present a constructive approach
to give modelers a choice of chemotactic sensitivity functionals,
production, and degradation terms for the chemical signal at hand.
The main aim is to understand the type of functionals and the interplay between them
that are needed for the traveling wave and pulse patterns to occur.
