Persistence and extinction for stochastic delay differential model of prey predator system with hunting cooperation in predators

Abstract: Stochastic differential models provide an additional degree of realism compared to their corresponding deterministic counterparts because of the randomness and stochasticity of real life. In this work, we study the dynamics of a stochastic delay differential model for prey-predator system with hunting cooperation in predators. Existence and uniqueness of global positive solution and stochastically ultimate boundedness are investigated. Some sufficient conditions for persistence and extinction, using Lyapunov f… Show more

“…Here R 0 = ξ η+α is known as the basic reproduction number of the deterministic model. In fact, there is an increasing indication that superior consistency with some phenomena can be contributed if the effects of environmental noises in the system are taken into account [34]. Epidemic model (1) assumes that the observed dynamics are driven exclusively by internal deterministic cases.…”

“…Based on the idea of the SIR framework, numerous types of mathematical models using compartmental approach have been developed in the meanwhile, all incorporating more structure and details of the transmission process and infectious disease dynamics [1,2,4]. Other authors use stochastic approach to models the dynamics and transmission of emergent and re-emergent infectious diseases [13,14]. In [13], the authors develop and study a stochastic approach to model the spread of COVID-19 epidemic by taking into account the cross immunity and time delay of transmission.…”

“…Thus, a qualitative analytical account to probe internal viral dynamics of SARS-CoV-2 virus with noise perturbations is yet under developmental stage and our research executions attempt to explore infection progression dynamics of SARS-CoV-2 virus with noise effects. Dynamical probes in model system inevitably evolving around their past states is widely acknowledged and concerning epidemiological studies, exquisite realistic dynamical expounds are achieved by executing analytical explorations inclusive of past states as time delay incorporation in model systems, render interesting exemplifications as seen in the works of [34] , [35] , [36] .…”
