Dynamical r-matrices for some nonlinear oscillators

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


Dynamical r-matrices for the Rosochatius and Wojciechowski systems are found. They appear as a product of reduction from the constant r-matrices for the coupled Neumann and the Gamier system, respectively. They serve also as alternative r-matrices for the Neumann system and the anharmonic oscillator (respectively), for which the constant r-matrices are known.
