Symmetry analysis for a class of nonlinear dispersive equations

K. Charalambous, C. Sophocleous

Research output: Contribution to journalArticlepeer-review


A class of dispersive equations is studied within the framework of group analysis of differential equations. The enhanced Lie group classification is achieved. The complete list of equivalence transformations is presented. It is shown that certain equations from the class admit nonclassical reductions. Potential and potential nonclassical symmetries are also considered.
