摘要

本文分析了SARS-CoV2冠状病毒感染过程中出现多波感染所必须具备的特点。根据上述感染人群数值的符号,建立了一个模型来模拟这一过程。当该符号不同于零时,得出关于感染、恢复和易感人群行为的结论,但当该符号为零时,对该过程建模的系统进行了简化,并应用微分方程定性理论得出了关于该过程行为的结论。最后,结合具体实例制作了相应的图表,证实了从理论角度得到的结果。

MATHEMATICAL MODELING OF THE APPEARANCE OF MULTIPLE WAVES IN THE SARS-COV-2 CORONAVIRUS
In this paper an analysis is made of the characteristics that the infection process by means of the SARS-CoV2 coronavirus must present so that multiple waves can appear. A model is made that simulates this process according to the sign of the preceding numerical value of the infected population. When the sign is different from zero, conclusions are reached regarding the behavior of infected, recovered and susceptible populations, but when this sign is zero, the system that models the process is simplified, and applying the qualitative theory of differential equations conclusions are reached regarding the behavior of the process. At the end, graphs are made corresponding to concrete examples that corroborate the results obtained from the theoretical point of view.
