Abstract:This paper studies a 2-species Lotka-Volterra model with cross-diffusion.The symmetry classification and symmetry reduction of the Lotka-Volterra model are considered by the generalized conditional symmetry.Then,the resulting Lotka-Volterra equations can be reduced to a system of ordinary differential equations.At last,the stability analysis and solutions of the Lotka-Volterra system are shown by two examples.
Key words:Symmetry classification;Symmetry reduction;Lotka-Volterra model;Stability analysis
