【Abstract】 This paper is devoted to the qualitative analysis of a model for the spread of gonorrhoea by using the singularity theory and Bendixson theorem. We provide the qualitative structure of the trajectories near the practical equilibrium points, in particular, near the higher order equilibrium point, study the global asymptotic stability of the practical equilibrium points and obtain the complete result.更多还原
