A note for global existence of a two-dimensional chemotaxis-haptotaxis model with remodeling of non-diffusible attractant

In this paper, we study the following coupled chemotaxis-haptotaxis model with remodeling of non-diffusible attractant in a bounded smooth domain with zero-flux boundary conditions, where χ, ξ and η are positive parameters. Under appropriate regularity assumptions on the initial data , by developing...

Summary:In this paper, we study the following coupled chemotaxis-haptotaxis model with remodeling of non-diffusible attractant in a bounded smooth domain with zero-flux boundary conditions, where χ, ξ and η are positive parameters. Under appropriate regularity assumptions on the initial data , by developing some Lp-estimate techniques, we prove the global existence and uniqueness of classical solutions when , where μ is the logistic growth rate of cancer cells. This result removes the additional restriction on μ, where μ is sufficiently large in Pang and Wang (2017 J. Differ. Equ. 263 1269-92) for the global existence of solutions.
