主 题：2019-nCov infectious model with advection reproductive number stability analysis numerical graphs
摘 要：Recently,the world is facing the terror of the novel corona-virus,termed as *** health institutes and researchers are continuously striving to control this *** this article,the SEIAR(susceptible,exposed,infected,symptomatically infected,asymptomatically infected and recovered)infection model of COVID-19 with a constant rate of advection is studied for the disease propagation.A simple model of the disease is extended to an advection model by accommodating the advection process and some appropriate parameters in the *** continuous model is transposed into a discrete numerical model by discretizing the domains,*** analyze the disease dynamics,a structure preserving non-standard finite difference scheme is *** steady states of the continuous system are described i.e.,virus free steady state and virus existing steady *** results show that both the steady states of the numerical design coincide with the fixed points of the continuous SEIAR *** of the state variables is ensured by applying the M-matrix theory.A result for the positivity property is *** the proposed numerical design,two different types of the stability are *** stability and linear stability for the projected scheme is examined by applying some standard *** Neuman stability test is applied to ensure linear *** reproductive number is described and its pivotal role in stability analysis is also *** and convergence of the numerical model is also *** graphs are presented via computer simulations to prove the worth and efficiency of the quarantine factor is explored graphically,which is helpful in controlling the disease *** the end,the conclusion of the study is also rendered.
