This work deals with the speed sign of travelling waves to the Lotka-Volterra model with diffusion and bistable nonlinearity. We obtain new conditions for the determinacy of the sign of the bistable wave speed by constructing upper or lower solutions with an inside parameter to be adjusted. The established conditions improve or supplement the results in the references and give insight into the combined effect of system parameters on the propagation direction of the bistable wave.

Lotka-Volterra竞争模型的双稳态波速。

这项工作处理了具有扩散和双稳态非线性的行波到Lotka-Volterra模型的速度符号。通过构造内部参数可调整的上下解,我们获得了确定双稳态波速符号的新条件。所建立的条件改善或补充了参考文献中的结果,并深入了解了系统参数对双稳态波传播方向的综合影响。
