Stability and Delays in a Predator-Prey System

Sufficient conditions for both local and global stability of the positive equilibrium in a predator-prey system with time delays are obtained by constructing suitable Lyapunov functionals. A remark on the mistake by K. N. Murty and M. A. S. Srinivas J. Math. Anal. Appl. 158, 1991, 333]341.is also included.
