Very recently, Atangana and Baleanu defined a novel arbitrary order derivative having a kernel of non-locality and non-singularity, known as derivative. We analyze a non-integer order Anthroponotic Leshmania Cutaneous (ACL) problem exploiting this novel derivative. We derive equilibria of the model and compute its threshold quantity, i.e. the so-called reproduction number. Conditions for the local stability of the no-disease as well as the disease endemic states are derived in terms of the threshold quantity. The qualitative analysis for solution of the proposed problem have derived with the aid of the theory of fixed point. We use the predictor corrector numerical approach to solve the proposed fractional order model for approximate solution. We also provide, the numerical simulations for each of the compartment of considered model at different fractional orders along with comparison with integer order to elaborate the importance of modern derivative. The fractional investigation shows that the non-integer order derivative is more realistic about the inner dynamics of the Leishmania model lying between integer order.
最近,Atangana 和 Baleanu 定义了一种具有非局部性和非奇异性核的新型任意阶导数,称为导数。我们利用这种新型导数来分析一个非整数阶的人源利什曼原虫皮肤(ACL)问题。我们导出了模型的平衡点,并计算了其阈值量,即所谓的繁殖数。利用阈值量推导出无病和地方病流行状态的局部稳定性条件。利用不动点理论推导出了所提出问题的解的定性分析。我们使用预测校正数值方法来求解所提出的分数阶模型的近似解。我们还针对所考虑模型的每个隔间在不同分数阶下提供了数值模拟,并与整数阶进行了比较,以阐述现代导数的重要性。分数阶研究表明,非整数阶导数更能反映利什曼模型的内部动力学,它位于整数阶之间。
