Benney-Roskes/Zakharov-Rubenchik System: Lie Symmetries and Exact Solutions
arXiv:2109.09695
Abstract
We investigate Lie symmetry algebra of the Benney-Roskes/Zakharov-Rubenchik systems. The invariance algebra turns out to be infinite-dimensional. We also find several exact solutions of periodic, line-soliton and stationary types.
