Bi-Hamiltonian Structures > s.a. integrable systems; quantum systems.
* Idea: (M, , H, ', H'), such that (, H) and (', H') induce the same Hamiltonian vector fields (equations of motion).
* Useful tensor: Can define the 1-1 tensor Sab:= 'acbc; satisfies X_H Sab = 0.
* Conserved quantities: Can be obtained by K0:= ln |det S|; Kn:= (1/n) tr Sn.
* Nijenhuis tensor: Defined using S, by

Nabm:= Sac c Sbm – Sbc c SamScm (a Sbcb Sac) ,

which is Lie-derived by XH. The system is integrable if N = 0.
