Abstract

In this paper, we consider a two-species parabolic-parabolic-elliptic chemotaxis system with weak competition and a fractional diffusion of order $s\in(0,2)$. It is proved that for $s>2p_{0}$, where $p_{0}$ is a nonnegative constant depending on the system's parameters, there admits a global classical solution. Apart from this, under the circumstance of small chemotactic strengths, we arrive at the global asymptotic stability of the coexistence steady state.

Keywords: Fractional chemotaxis, Lotka-Volterra competition, global classical solution, asymptotic stability
