Recent studies demonstrate that the density of prey population is not only affected by direct
killing by the predator, but the fear in prey caused by predator also reduces it by cutting …

In this survey, we briefly review some of our recent studies on predator-prey models with
discrete delay. We first study the distribution of zeros of a second degree transcendental …

We investigate the dynamics of a prey–predator model with cooperative hunting among
specialist predators and maturation delay in predator growth. First, we consider a model …

In the present work, we investigate on the dynamics of predator–prey model with prey refuge
in proportion to both species and the effect of additional food provided to the predator. A …

In this paper, we consider a two-dimensional prey-predator system with two delays. One
delay is for negative feedback of the prey population and another is for gestation delay of the …

This study proposes a three-dimensional prey–predator model with stage structure in prey
(immature and mature) including maturation delay in prey population and gestation delay in …

Discrete time delay has been widely used in models of interacting populations to capture
various biological processes such as gestation, maturation, food digestion, disease …

In the present paper, we study the effect of gestation delay on a tri-trophic food chain model
with Holling type-II functional response. The essential mathematical features of the proposed …

Time delay is an inevitable factor in neural networks due to the finite propagation velocity
and switching speed. Neural system may lose its stability even for very small delay. In this …

We study the stability of a delay susceptible–infective–recovered epidemic model with time
delay. The model is formulated under the assumption that all individuals are susceptible …
