This article describes the corona virus spread in a population under certain assumptions with the help of a fractional order mathematical model. The fractional order derivative is the well-known fractal fractional operator. We have given the existence results and numerical simulations with the help of the given data in the literature. Our results show similar behavior as the classical order ones. This characteristic shows the applicability and usefulness of the derivative and our numerical scheme.

SE(Is)(Ih)AR流行分数阶COVID-19模型的数值分析研究

本文借助分数阶数学模型描述了在某些假设下冠状病毒在人群中的传播。分数阶导数是众所周知的分形分数算子。我们借助文献中给定的数据给出了存在性结果和数值模拟。我们的结果显示出与经典顺序相似的行为。这个特性表明了导数和我们的数值方案的适用性和有用性。
