Abstract:
We examine a class of attraction-repulsion chemotaxis models, which are defined by nonlinearities in the diffusion of cell density, chemosensitivity, and the production rates of chemoattractants and chemorepellents. Additionally, the model includes a logistic term that also depends on the gradient of the biological distribution. In this presentation, we will establish a condition for their boundedness.
