Abstract

In this paper, we investigate properties of solutions to a space-time fractional variable-order conformable nonlinear differential equation with a generalized tempered fractional Laplace operatorby using the maximum principle. We first establish some new important fractional various-order conformable inequalities. With these inequalities, we prove a new maximum principle with space-time fractional variable-order conformable derivatives and a generalized tempered fractional Laplace operator. Moreover, we discuss some results about comparison principles and properties of solutions for a family of space-time fractional variable-order conformable nonlinear differential equations with a generalized tempered fractional Laplace operator by maximum principle.

具有广义调质分数阶拉普拉斯算子的变阶分数阶可合微分方程的极大值原理

本文利用极大值原理研究了一类具有广义调质分数阶拉普拉斯算子的空时分数阶变阶可合非线性微分方程解的性质。首先建立了一些新的重要的分数阶可适应不等式。利用这些不等式，我们证明了一个新的时空分数阶变阶可调导数的极大原理和一个广义调质分数阶拉普拉斯算子。此外，利用极大值原理讨论了一类具有广义调质分数阶拉普拉斯算子的时空分数阶变阶可调非线性微分方程解的比较原理和性质。
