On deformations of standard R-matrices for integrable infinite-dimensional systems
arXiv:nlin/0501044 · doi:10.1063/1.1868373
Abstract
Simple deformations, with a parameter , of classical -matrices which follow from decomposition of appropriate Lie algebras, are considered. As a result nonstandard Lax representations for some well known integrable systems are presented as well as new integrable evolution equations are constructed.
