I have one question. If I have Hamiltonian:

H=\sum^{f_1}_{i=1}\alpha_iq_i^2+\sum^{f_2}_{i=1}\b eta_ip_i^2

I can show that for the Hamiltonian of this type equipartition theorem is correct. Is there any Hamiltonian which is not a function od squares of coordinates and impulses are from which I can get this Hamiltonian some using canonical transformation. Example perhaps?

What does it mean "equipartition theorem is correct" ?
I think the hamiltonian is both integrable and separable, since it's not ergodic does the ensemble averages have sense?

You can prove that every degree of fredom have the same energy - equipartition theorem only for the Hamiltonian


H=\sum^{f_1}_{i=1}\alpha_iq_i^2+\sum^{f_2}_{i=1}\b eta_ip_i^2


or maybe the Hamiltonian which canonical transformation is



H=\sum^{f_1}_{i=1}\alpha_iq_i^2+\sum^{f_2}_{i=1}\b eta_ip_i^2


I think that ''
mysterious '' Hamiltonian have the same form as one as I wrote! So for example



K=\sum^{F_1}_{i=1}\alpha_iQ_i^2+\sum^{F_2}_{i=1}\b eta_iP_i^2


Am I right?
