Abstract: |
By employing the Lyapunov-Razumikhin technique,we consider the existence,uniqeness and global attractivity of positive periodic solution of multispecies ecological competition predator system with periodic coefficients and continuous time delay. |
Key words: competition-predator system periodic solution global attractivity multispecies ecological |
