Reeb vector field

In mathematics, the Reeb vector field, named after the French mathematician Georges Reeb, is a notion that appears in various domains of contact geometry including:

• in a contact manifold, given a contact 1-form [math]\displaystyle{ \alpha }[/math], the Reeb vector field satisfies [math]\displaystyle{ R \in \mathrm{ker }\ d\alpha, \ \alpha (R) = 1 }[/math],
• in particular, in the context of Sasakian manifold.
