Persistence of two weak competing species in a shifting environment (Q2143515)

The author study the persistence of two weak competing species in a shifting environment. An interesting Liouville type theorem on the entire solution of the weak competition system is proved (see Proposition 2.1). The main result also extends the former works of \textit{Y. Yuan} et al. [Discrete Contin. Dyn. Syst., Ser. B 24, No. 10, 5633--5671 (2019; Zbl 1421.92038)] and \textit{Z. Zhang} et al. [Nonlinear Anal., Model. Control 22, No. 3, 285--302 (2017; Zbl 1416.92147)].
