A predator-prey model with strong Allee effect and disease in prey population
The main objective of this paper is to study the dynamical behaviour of a ratio-dependent predator-prey model with disease in prey. We have also incorporated a strong Allee effect. The total prey population is divided into two subdivisions, namely susceptible prey population and infected prey population. It is assumed that both the prey populations are consumed by the predator. The positivity and uniform boundedness of the dynamical system
are discussed. We have analysed stability of the equilibrium points. It is also pointed out that around an interior equilibrium point a Hopf-bifurcation has occurred considering susceptible prey survival threshold parameter as bifurcating parameter. To verify our analytical findings, numerical simulations are carried out using MATLAB.

Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
