RT Journal Article T1 Lie symmetries versus integrability in evolution equations A1 Abellanas RapĂșn, Lorenzo A1 MartĂ­nez Ontalba, Celia AB Motivated by some recent results obtained concerning the invariance properties of a particular family of generalized KdV equations, we investigate the possible significance of classical Lie invariance groups as a test for complete integrability.
