On the connections between Ruijsenaars-Schneider systems and other areas
the integrable systems in question are complexified, so for an n-body model (say Ruijsenaars-Schneider) the phase space is $4n$ real ($2n$ complex)-dimensional. If the coordinates and conjugate moment …

What is an integrable system?
I would like to add one more example of integrability which refers to Hopf algebras and is probably the easiest to formulate. It naturally arises in spin chain physics, but can be treated abstractly a …
