| 英文摘要 | For the Harry Dym equation, there exist four sets of time-independent symmetries and one set of the master symmetries. The negative half-hierarchy of the master symmetries are also the time-independent symmetries. All these symmetries constitute an infinite-dimensional Lie algebra. Four hierarchies of integrable models possess one common recursion operator and one set of common symmetries. Only usual Harry Dym hierarchy, which contains the Harry Dym equation, possesses four sets of time-independent symmetries, while other three integrable hierarchies possess only two sets of time-independent symmetries. |
