Abstract

In this study‎, ‎we investigate codimension-two bifurcations in a discrete predator--prey model‎. ‎First‎, ‎we provide a theoretical analysis of several bifurcation types‎, ‎including $1{:}2$‎, ‎$1{:}3$‎, ‎and $1{:}4$ resonances‎, ‎generalized flip bifurcations‎, ‎and generalized Neimark--Sacker bifurcations‎. ‎Using the center manifold theory and normal form reduction‎, ‎the conditions for the occurrence of these bifurcations are derived‎. ‎Subsequently‎, ‎numerical simulations are performed with the MatcontM package in MATLAB to validate the analytical results‎. ‎The findings offer a comprehensive view of the complex dynamics arising from codimension-two bifurcations in biological interaction systems‎.
