BTL和CTL体系的平方本征函数对称性
Squared Eigenfunction Symmetries for the BTL and CTL Hierarchies
摘要：
本文考虑BTL和CTL的约束条件，通过对TL族的平方特征函数对称性进行适当的修改，显式地构造了BTL和CTL族的平方特征函数对称性.此外，与相应的额外的对称性的连接进行了调查：平方本征函数对称性产生的波函数可以被视为生成函数的额外的对称性。
英文摘要：
In this paper, the squared eigenfunction symmetries for the BTL and CTL hierarchies are explicitly constructed with the suitable modification of the ones for the TL hierarchy, by considering the BTL and CTL constraints. Also the connections with the corresponding additional symmetries are investigated: the squared eigenfunction symmetry generated by the wave function can be viewed as the generating function for the additional symmetries.
