3/2-type criteria for global attractivity of Lotka–Volterra competition system without instantaneous negative feedbacks

This paper deals with a two-species Lotka–Volterra competition model with discrete delays but without instantaneous negative feedbacks. Motivated by Wrightʹs global attractivity result for the delayed scalar logistic equation, we establish some new -type criteria for global attractivity of the positive equilibrium of the system. These criteria provide convenient and better (than some existing) estimates for the diagonal delays.
