Abstract

In this paper we study a nonlinear infection viral propagation model with diffusion, in which, the left boundary is fixed and with homogeneous Dirichlet boundary conditions, while the right boundary is free. We find that the habitat always expands to the half line $[0, \infty)$ , and that the virus and infected cells always die out when the Basic Reproduction Number $R_{0} \leq 1$ , while the virus and infected cells have persistence properties when $R_{0} > 1$ . To obtain the persistence properties of virus and infected cells when $R_{0} > 1$ , the most work of this paper focuses on the existence and uniqueness of bounded positive equilibrium solutions for subsystems and the existence of positive equilibrium solutions for the entire system.

具有一个固定边界和一个自由边界的非线性感染病毒传播模型的动力学特性

在本文中，我们研究了一个具有扩散作用的非线性感染病毒传播模型，其中，左边界是固定的，具有同质 Dirichlet 边界条件，而右边界是自由的。为了获得 R0>1 时病毒和受感染细胞的持续特性，本文的大部分工作集中于子系统有界正平衡解的存在性和唯一性以及整个系统正平衡解的存在性。

期刊介绍： The journal publishes original research findings on experimental observation, mathematical modeling, theoretical analysis and numerical simulation, for more accurate description, better prediction or novel application, of nonlinear phenomena in science and engineering. It offers a venue for researchers to make rapid exchange of ideas and techniques in nonlinear science and complexity. The submission of manuscripts with cross-disciplinary approaches in nonlinear science and complexity is particularly encouraged. Topics of interest: Nonlinear differential or delay equations, Lie group analysis and asymptotic methods, Discontinuous systems, Fractals, Fractional calculus and dynamics, Nonlinear effects in quantum mechanics, Nonlinear stochastic processes, Experimental nonlinear science, Time-series and signal analysis, Computational methods and simulations in nonlinear science and engineering, Control of dynamical systems, Synchronization, Lyapunov analysis, High-dimensional chaos and turbulence, Chaos in Hamiltonian systems, Integrable systems and solitons, Collective behavior in many-body systems, Biological physics and networks, Nonlinear mechanical systems, Complex systems and complexity. No length limitation for contributions is set, but only concisely written manuscripts are published. Brief papers are published on the basis of Rapid Communications. Discussions of previously published papers are welcome.
