Symplectization
In mathematics, the symplectization of a contact manifold is a symplectic manifold which naturally corresponds to it.
== Definition ==

Let (V,\xi) be a contact manifold, and let x \in V. Consider the set
: S_xV = \ \subset T^
*_xV
of all nonzero 1-forms at x, which have the contact plane \xi_x as their kernel. The union
:SV = \bigcup_S_xV \subset T^
*V
is a symplectic submanifold of the cotangent bundle of V, and thus possesses a natural symplectic structure.
The projection \pi : SV \to V supplies the symplectization with the structure of a principal bundle over V with structure group \R^
* \equiv \R - \.
