摘要

The conformable fractional derivative was proposed by R. Khalil et al. in 2014, which is natural and obeys the Leibniz rule and chain rule. Based on the properties, a class of time-fractional partial differential equations can be reduced into ODEs using traveling wave transformation. Then the simplest equation method is applied to find exact solutions of some time-fractional partial differential equations. The exact solutions (solitary wave solutions, periodic function solutions, rational function solutions) of time-fractional generalized Burgers equation, time-fractional generalized KdV equation, time-fractional generalized Sharma-Tasso-Olver (FSTO) equation and time-fractional fifth-order KdV equation, (3 + 1)-dimensional time-fractional KdV-Zakharov-Kuznetsov (KdV-ZK) equation are constructed. This method presents a wide applicability to solve some nonlinear time-fractional differential equations with conformable derivative. (C) 2018 Elsevier Ltd. All rights reserved.

Khalil等人提出了合适的分数导数。在2014年,这是自然而然的,并遵守莱布尼兹(Leibniz)规则和连锁规则。基于这些性质,可以使用行波变换将一类时间分数阶偏微分方程简化为ODE。然后,应用最简单的方程方法找到一些时分偏微分方程的精确解。时间分数阶广义Burgers方程,时间分数阶KdV方程,时间分数阶Sharma-Tasso-Olver(FSTO)方程和时间分数阶五阶方程的精确解(孤波解,周期函数解,有理函数解)构造KdV阶方程,构造(3 +1)维时间分数KdV-Zakharov-Kuznetsov(KdV-ZK)方程。该方法具有广泛的适用性,可以求解一些具有相合导数的非线性时间分数阶微分方程。 (C)2018 Elsevier Ltd.保留所有权利。
