| Abstract: | By the local bifurcation theory and stability theory,the local bifurcation and stability of steady-state solutions in(prey-predator) model with(Beddington-DeAngelis) response and Dirichlet boundary conditions are studied.Furthermore,sufficient conditions for the existence of positive(steady-state) solutions and its stability are obtained. |

| Keywords: | local bifurcation semi-trivial steady-state solutions stability |
