Effect of Delay on Single Population with Infection in Polluted Environment
In this paper, we have studied mathematical model for single-species population which is infected by viral disease under the influence of polluted environment. We consider that the population is divided into two classes i.e., susceptible and infective. The boundedness of the system is discussed. The existence of equilibrium points and their local stability is analyzed. Further, we have also studied the existence of Hopf-bifurcation. We have derived a threshold T10 below which the positive equilibrium point is locally asymptotically stable and at T10, it undergoes Hopf bifurcation. Finally, we verified the theoretical results with the help of numerical simulations.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. 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. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
