New solitary wave solutions of (2+l)-dimensional space-time fractional Burgers equation and Korteweg-de Vries equation

摘要

In this article, via the improved fractional subequation method, the fully analytical solutions of the (2+1)-dimensional space-time fractional Burgers equation and Korteweg-de Vries equation involving Jumarie's modified Riemann-Liouville derivative have been derived. As a result, with the aid of symbolic computation, many types of new analytical solutions are obtained, which include new solitary wave, periodic wave and rational wave solutions. The graphical representations show that these gained solutions have abundant structures. (C) 2018 Elsevier Ltd. All rights reserved.
