| Abstract: | The two-group competition model with non-local diffusion in a class of classic Lotka-Volterra system is studied.First,turning it into a collaborative system,under the condition that the monostable condition is satisfied,by constructing various new upper and lower solutions,it obtains new results that the minimum wave velocity of the system is linear or nonlinear,and the relationship between the parameters under the linear and nonlinear selection. |
