ABSTRACT
The purpose of this paper is to describe the direction and stability of nonconstant periodic solutions from a positive equilibrium for the predator-prey system with discrete delay () { M ˙ ( t ) = M ( t ) [ a − b M ( t ) − c N ( t ) ] , N ˙ ( t ) = l N ( t ) [ M ( t − r ) − β ] , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003067498/6ba0c26b-f086-40cc-86ed-1693dc596221/content/eq1367.tif"/>
