BIFURCATION AND COMPLEX DYNAMICS OF A DISCRETE-TIME PREDATOR-PREY SYSTEM INVOLVING GROUP DEFENSE

In this paper, we investigate the dynamics of a discrete-time gewehr 91 predator-prey system involving group defense.The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by

BACKGROUND: Adolescent pregnancy remains to be a significant social and public health problem in the Philippines, despite the widespread implementation of a comprehensive sexual and reproductive health (SRH) law.The current study explored the perceptions on teenage pregnancy and adolescent-oriented services across different views of stakeholders.MA
