摘要
Ⅰ. INTRODUCTION In Ref. [1], the symmetries and integrability of the G-KdV equation are considered. The authors give the Lax pair, the first three classical symmetries K0, K1, K2 and the first three new symmetries τ1, τ2, τ3 of the C-KdV equation and point out that these symmetries satisfy a graded Lie algebra.
