Abstract:
We study a class of zero-flux attraction-repulsion chemotaxis models, characterized by nonlinearities laws for the diffusion of the cell density, the chemosensitivities and the production rates of the chemoattractant and the chemorepellent. Additionally, a source involving also the gradient of the biological distribution is incorporated. In this talk we will see a sketch of the proof for the existence of solutions and we will find a condition for the boundedness.
