In classical integrable models, in the discrete case we have the Sklyanin algebra,
{Ta(u),Tb(v)}=[rab(u,v),Ta(u)Tb(v)].{Ta(u),Tb(v)}=[rab(u,v),Ta(u)Tb(v)].
How to prove that the conserved quantities are generated from ln(τ(u))ln(τ(u)) in the periodic case, which are the integrable models (long-range) or condition which is not this expression which provide us the local conserved quantities in the Arnold-Liouville theorem?

The main reason is to prove the formulae(s) given below.
- {Ta(u),Tb(v)}=[rab(u,v),Ta(u)Tb(v)].
- {Ta(u),Tb(v)}=[rab(u,v),Ta(u)Tb(v)].
- (τ(u))ln(τ(u))
