K symmetries and $\tau$ symmetries of evolution equations and their Lie algebras.
(English)
[J] J. Phys. A, Math. Gen. 23, No.13, 2707-2716 (1990). ISSN 0305-4470

Summary: On the basis of Tu's work [see {\it Guizhang Tu}, J. Phys. A 21, No.9, 1951-1957 (1988; Zbl 0662.35103)] we establish a more general skeleton on K symmetries and $\tau$ symmetries of evolution equations and their Lie algebraic structures and discuss carefully the corresponding symmetries and Lie algebras for KdV and Jaulent-Miodek hierarchies.
MSC 2000:
*35Q53 KdV-like equations
17B65 Infinite-dimensional Lie algebras

Keywords: Korteweg-de Vries hierarchy; symmetries
