In this paper, we derive three conservation laws and three invariants of motion for the generalized Gardner equation … derivation of these conservation laws and their associated invariants of motion is direct and does not involve the use of … variational principles. It can be easily applied for finding similar invariants of motion for other general types of KdV, Gardner …
