Mathematics, Sciences An isomorphism of a symplectic manifold; a diffeomorphism which preserves symplectic structure.
- In prequantizing symplectomorphisms of the type T^*g, the only special property which we used was the fact that they preserve canonical 1-forms.1977, Alan Weinstein, Lectures on Symplectic Manifolds, American Mathematical Society, page 34:
- Poincare's argument is based on the fact that the fixed points of a symplectomorphism of the annulus are precisely the critical points of the function #92;textstyleF(x,y)#61;#92;int#123;(fdv-gdu)#125;, where u#61;(X#43;x)#47;2, v#61;(Y#43;y)#47;2, true under the assumption that the Jacobian #92;partial(u,v)#47;#92;partial(x,y) is different from zero.2001, V.
