摘要

摘要本文考虑了幂律分形分数微分算子的Cauchy问题、指数衰减和广义Mittag-Lefler核。我们从导出一些重要的不等式开始，然后通过使用线性增长和Lipchitz条件，我们导出了这些方程允许唯一解的条件。对于每种情况，都提出了一个数值方案来推导方程的数值解。给出了分形分数阶微分方程的一些例子，得到了它们的精确解，并与所用的数值格式进行了比较。考虑并求解了一个非线性情况，给出了不同阶数和分形维数的数值解。

Analysis of Cauchy problem with fractal-fractional differential operators

Abstract Cauchy problems with fractal-fractional differential operators with a power law, exponential decay, and the generalized Mittag-Leffler kernels are considered in this work. We start with deriving some important inequalities, and then by using the linear growth and Lipchitz conditions, we derive the conditions under which these equations admit unique solutions. A numerical scheme was suggested for each case to derive a numerical solution to the equation. Some examples of fractal-fractional differential equations were presented, and their exact solutions were obtained and compared with the used numerical scheme. A nonlinear case was considered and solved, and numerical solutions were presented graphically for different values of fractional orders and fractal dimensions.
