Abstract

Previous studies of chemotaxis models with consumption of the chemoattractant (with or without fluid) have not been successful in explaining pattern formation even in the simplest form of concentration near the boundary, which had been experimentally observed. Following the suggestions that the main reason for that is the usage of inappropriate boundary conditions, in this paper we study the solutions to the stationary chemotaxis system [Formula: see text] in bounded domains [Formula: see text], [Formula: see text], under the no-flux boundary conditions for [Formula: see text] and the physically meaningful condition [Formula: see text] on [Formula: see text], with the given parameter [Formula: see text] and [Formula: see text], [Formula: see text], satisfying [Formula: see text], [Formula: see text] on [Formula: see text]. We prove the existence and uniqueness of solutions for any given mass [Formula: see text]. These solutions are nonconstant.
