Group Theoretical Symmetries and Generalized Baecklund Transformations for Integrable Systems
arXiv:hep-th/9209004 · doi:10.1063/1.530508
Abstract
We present a notion of symmetry for 1+1-dimensional integrable systems which is consistent with their group theoretic description and reproduces in special cases the known Baecklund transformation for the generalized Korteweg-deVries hierarchies. We also apply it to the relativistic invariance of the Leznov-Saveliev systems.
