Modelling of a two prey and one predator system with switching effect
Computational and Mathematical Biophysics, 2021 Prey switching strategy is adopted by a predator when they are provided with more than one prey and predator prefers to consume one prey over others. Though switching may occur due to various reasons such as scarcity of preferable prey or risk in hunting

Oscillatory bifurcation problems for ODEs with logarithmic nonlinearity
Open Mathematics, 2021 We study the global structure of the oscillatory perturbed bifurcation problem which comes from the stationary logarithmic Schrödinger equation −u″(t)=λ(log(1+u(t))+sinu(t)),u(t)>0,t∈I≔(−1,1),u(±1)=0,-{u}^{^{\prime\prime} }\left(t)=\lambda (\log \left(1 ...

Bifurcations and exact traveling wave solutions for the regularized Schamel equation
Open Mathematics, 2021 In the present paper, we focus on studying the bifurcations and the traveling wave solutions (TWSs) for the regularized Schamel equation. Based on the bifurcation method of a dynamical system, a complete phase portrait analysis is given in various ...

Impact of fear in a prey-predator system with herd behaviour
Computational and Mathematical Biophysics, 2021 Fear of predation plays an important role in the growth of a prey species in a prey-predator system. In this work, a two-species model is formulated where the prey species move in a herd to protect themselves and so it acts as a defense strategy.
