Permanence and asymptotic properties of fuzzy stochastic delay Lotka-Volterra model

Qimin Zhang, Shuo Ma, Hongfu Yang

Abstract


In this paper, a class of fuzzy stochastic delay Lotka-Volterra model is investigated. Applying Ito’s formula, we show that the fuzzy stochastic delay Lotka-Volterra model is stochastically permanent. Moreover, we obtain that the limit of the average in time of the sample path of the solution is estimated by two constants. Finally, the main results are illustrated by several examples.

Keywords

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.
