Time-fractional generalized fifth-order KdV equation: Lie symmetry analysis and conservation laws
The purpose of this study is to apply the Lie group analysis method to the time-fractional order generalized fifth-order KdV (TFF-KdV) equation. We examine applying symmetry analysis to the TFF-KdV equation with the Riemann–Liouville (R–L) derivative, employing the G ′/ G -expansion approach to yiel...

Summary: | The purpose of this study is to apply the Lie group analysis method to the time-fractional order generalized fifth-order KdV (TFF-KdV) equation. We examine applying symmetry analysis to the TFF-KdV equation with the Riemann–Liouville (R–L) derivative, employing the
G
′/
G
-expansion approach to yield trigonometric, hyperbolic, and rational function solutions with arbitrary constants. The discovered solutions are unique and have never been studied previously. For solving non-linear fractional partial differential equations, we find that the
G
′/
G
-expansion approach is highly effective. Finally, conservation laws for the equation are well-built with a full derivation based on the Noether theorem. |
