Large time convergence for a chemotaxis model with degenerate local sensing and consumption

Analysis of PDEs 2023-04-04 v1

Abstract

Convergence to a steady state in the long term limit is established for global weak solutions to a chemotaxis model with degenerate local sensing and consumption, when the motility function is C^1-smooth on [0, \infty), vanishes at zero, and is positive on (0, \infty). A condition excluding that the large time limit is spatially homogeneous is also provided. These results extend previous ones derived for motility functions vanishing algebraically at zero and rely on a completely different approach.
