摘要
本文深入探讨了分数微积分在使用常微分方程的流行病学模型中的应用,重点是卡普托导数。它强调了卡普托导数在模拟具有记忆效应的复杂系统中发挥的关键作用,并评估了各种流行病学模型,包括 SIR 变体,展示了卡普托导数如何捕捉真实流行病中的分数阶动态和记忆现象。这项研究展示了拉普拉斯变换在分析由带有卡普托导数的常微分方程描述的系统时的实用性。这种方法有助于采用分析和数值方法进行系统分析和参数估计。此外,论文还介绍了流行病学模型的表格表示法,从而能够对变量关系和动态进行可视化和分析性探索。这种基于矩阵的框架允许应用线性代数技术来评估稳定性和平衡点,从而为长期行为和控制策略提供有价值的见解。总之,这项研究强调了卡普托导数、拉普拉斯变换和矩阵表示法在流行病学建模中的重要性。我们假定,在某些情况下,将函数视为常数时,通过使用这类方法,我们可以用手得到解析解,而无需寻找数值方法。
Applying Laplace Transformation on Epidemiological Models as Caputo Derivatives
This paper delves into the application of fractional calculus, with a focus on Caputo derivatives, in epidemiological models using ordinary differential equations. It highlights the critical role Caputo derivatives play in modeling intricate systems with memory effects and assesses various epidemiological models, including SIR variants, demonstrating how Caputo derivatives capture fractional-order dynamics and memory phenomena found in real epidemics. The study showcases the utility of Laplace transformations for analyzing systems described by ordinary differential equations with Caputo derivatives. This approach facilitates both analytical and numerical methods for system analysis and parameter estimation. Additionally, the paper introduces a tabular representation for epidemiological models, enabling a visual and analytical exploration of variable relationships and dynamics. This matrix-based framework permits the application of linear algebra techniques to assess stability and equilibrium points, yielding valuable insights into long-term behavior and control strategies. In summary, this research underscores the significance of Caputo derivatives, Laplace transformations, and matrix representation in epidemiological modeling. We assume that by using this type of methodology we can get analytic solutions by hand when considering a function as constant in certain cases and it will not be necessary to search for numerical methods.
