Web1 Answer. Sorted by: 2. The orbits of the flow by the vector field X forms a foliation F X of T 2. There is a transverse measure to the foliation: for a curve σ transverse to F X, define the measure of σ to be ∫ σ i X μ. Since the vector field X and 2-form μ are preserved by the flow by X, this measure is invariant under the flow by X ...
