Lie symmetry reductions and group invariant solutions of (2 + 1)-dimensional modified Veronese web equation
Sachin Kumar,Amit Kumar +1 more
TL;DR: In this article, the authors applied the Lie symmetry method to compute group invariant solutions for the modified Veronese web (mVw) equation and obtained its infinitesimals, commutation table of Lie algebra, symmetry reductions and closed form analytical solutions.
Journal ArticleDOI
Lie symmetry analysis for obtaining the abundant exact solutions, optimal system and dynamics of solitons for a higher-dimensional Fokas equation
TL;DR: In this article, the Lie group of transformation method via one-dimensional optimal system is proposed to obtain some more exact solutions of the (4+1)-dimensional Fokas equation.
Journal ArticleDOI
New exact solitary wave solutions of the strain wave equation in microstructured solids via the generalized exponential rational function method
TL;DR: In this article, the generalized exponential rational function method was used to obtain exact solitary wave solutions in various forms of the strain wave equation, including multiple-solitons, bell-shaped solitons, traveling waves, trigonometric and rational solutions.
