On deformations of standard R-matrices for integrable infinite-dimensional systems
Blazej M. Szablikowski, Maciej Blaszak
Abstract
Simple deformations, with a parameter ε, of classical R-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.
