In this manuscript, we solve a model of the novel coronavirus (COVID-19) epidemic by using Corrector-predictor scheme. For the considered system exemplifying the model of COVID-19, the solution is established within the frame of the new generalized Caputo type fractional derivative. The existence and uniqueness analysis of the given initial value problem are established by the help of some important fixed point theorems like Schauder's second and Weissinger's theorems. Arzela-Ascoli theorem and property of equicontinuity are also used to prove the existence of unique solution. A new analysis with the considered epidemic COVID-19 model is effectuated. Obtained results are described using figures which show the behaviour of the classes of projected model. The results show that the used scheme is highly emphatic and easy to implementation for the system of non-linear equations. The present study can confirm the applicability of the new generalized Caputo type fractional operator to mathematical epidemiology or real-world problems. The stability analysis of the projected scheme is given by the help of some important lemma or results.
在本手稿中,我们使用校正-预测格式求解了新型冠状病毒(COVID-19)疫情模型。对于所考虑的体现COVID-19模型的系统,其解是在新的广义Caputo型分数阶导数框架内建立的。借助一些重要的不动点定理,如绍德第二定理和魏辛格定理,对给定初值问题进行了存在性和唯一性分析。阿尔泽拉-阿斯科利定理和等度连续性性质也被用于证明唯一解的存在性。对所考虑的COVID-19疫情模型进行了新的分析。使用图表描述了所得结果,这些图表展示了预测模型各类别的行为。结果表明,所使用的格式对于非线性方程组系统具有高度的有效性且易于实现。本研究可以证实新的广义Caputo型分数阶算子在数学流行病学或实际问题中的适用性。借助一些重要的引理或结果给出了预测格式的稳定性分析。
