In this work, we have introduced a tritrophic food-chain model where consumer hunt for prey with Holling type-III functional response. The birth rate of the population has been reduced due to fear predation, i.e., effect is considered in population. Moreover, fraction available consumption and done by incorporation refuge term. predation between predator follows Beddington-DeAngelis Boundedness...

This paper investigates the global stability of virus dynamics model with BeddingtonDeAngelis infection rate. By constructing Lyapunov functions, the global properties have been analyzed. If the basic reproductive ratio of the virus is less than or equal to one, the uninfected steady state is globally asymptotically stable. If the basic reproductive ratio of the virus is more than one, the infe...
