The following question seems to be simple enough...Anyway, I hope if someone could confirm what I am thinking.
Is canonical transformation in mechanics unique? We know that given [tex]\ (q, p)\rightarrow\ (Q, P)[/tex], [tex]\ [q,p] = [Q,P] = constant[/tex] and Hamilton's equations of motion stay the same in the new co-ordinates.
My question is: given [tex]\ q\rightarrow Q[/tex] in a canonical transoformation, is the map [tex]\ p\rightarrow P[/tex] uniquely determined? Seems yes to me, but I do not find an off-hand argument in favour.
Can anyone tell how to derive this map?
