摘要

本文分析了一个年龄组 SIR(易感者-感染者-康复者)模型。得出了有关总人口守恒性、解析解的正相关性和流行病最终规模的理论结果。由于该模型是一个非线性常微分方程系统,因此考虑了基于标准和非标准有限差分法以及修正帕坦卡欧拉法的数值近似。研究了在数值上如何保持解析解的定性特性。所得结果被应用于社交网络中的信息扩散。通过对真实数据进行多次数值测试,证明了不同数值方法的有效性。

Analytical Properties and Numerical Preservation of an Age-Group Sir Model: Application to the Diffusion of Information
This paper analyzes an age-group SIR (Susceptible-Infected-Recovered) model. Theoretical results concerning the conservation of the total population, the positivity of the analytical solution, and the final size of the epidemic are derived. Since the model is a nonlinear system of ordinary differential equations, a numerical approximation is considered, based on Standard and non Standard Finite Difference methods, and on the Modified Patankar Euler method. The numerical preservation of the qualitative properties of the analytical solution is studied. The obtained results are applied to the diffusion of information in social networks. The effectiveness of the different numerical approaches is shown through several numerical tests on real data.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
