Paper Title
Study of Chaotic Dynamics with Group Defense in a Predator- Prey System: A Mathematical Modeling Approach

Abstract
The main objective of the present paper is to study a tri-trophic predator–prey model of one prey and two predators exhibiting group defense mechanism. Monod-Haldane functional response is used for interaction between species due to group defense ability of prey and middle predator. The model system is investigated analytical as well as numerically. The local and global stability analysis is carried out. The numerical results are presented in the form of phase portrait, 2D scan and bifurcation analysis. The numerical simulations shows the chaotic and periodic oscillations of the model system for certain range of parameter.
