Equilibration in a two-species-two-chemicals chemotaxis-competition system
This paper deals with the two-species--two-chemicals chemotaxis-competition system with signal-dependent sensitivity,
where Ω is a bounded domain in Rn (n ≥ 2) with smooth boundary, χ1,χ2 and μ1,μ2 are constants satisfying some conditions. About this system Tu–Mu–Zheng–Lin (Discrete Contin. Dyn. Syst.;2018;38;3617– 3636) showed global existence and stabilization of solutions under some smallness conditions for χ1 and χ2. Here energy arguments for seeing stabilization in the previous work were based on ideas in Bai–Winkler (Indiana Univ. Math. J.;2016;65;553–583); however, these ideas were recently improved by the first author (Discrete Contin. Dyn. Syst. Ser. S;2020;13;269–278), which implies that the result about stabilization in the previous work seems not to be the best. This paper gives an improve- ment of conditions for stabilization in the previous work. The feature of the proof is to use the Sylvester criterion in deriving energy estimates.
