Abstract
In this section, we denote by P a manifold, and denote the cotangent bundle on P by \(T^{*}P\). The fiber \(T^{*}_xP\) of \(T^{*}P\) at any point \(x\in P\) is the dual space of the vector space \(T_xP\), and the elements in \(T^{*}_xP\) are the cotangent vectors at the point x. We use \(\pi \) and \(\pi _{*}\) to denote the projections of TP and \(T^{*}P\) on P respectively. We use \(T(T^{*}P)\) to denote the tangent bundle of the cotangent bundle \(T^{*}P\) and use \(\pi _0\) to denote the projection of \(T(T^{*}P)\) on the base space \(T^{*}P\).

Added by the authors of the Forewords. This vector field, which can be defined on the total space of any vector bundle, is often called the Liouville vector field in other texts.
