A note on optimal systems of certain low-dimensional Lie algebras
(De Gruyter Open Ltd, 2020-12-22)Optimal classifications of Lie algebras of some well-known equations under their group of inner automorphism are re-considered. By writing vector fields of some known Lie algebras in the abstract format, we have proved ... -
On invariant analysis and conservation laws for degenerate coupled multi-KdV equations for multiplicity l= 3
(Springer, 2019)The degenerate coupled multi-Korteweg–de Vries equations for coupled multiplicity l= 3 are studied. The equations, also known as three-field Kaup–Boussinesq equations, are considered for invariant analysis and conservation ...
