that is, the problem of finding a function u on M whose derivative along the flow is equal to a given function f on M . Roughly speaking, the Ccohomology of the flow is the space of non-trivial obstructio ns to the existence of aC solutionu of (1.1) for any given functionf ∈ C(M). This notion is well-defined if the range of the Lie derivative operator on… CONTINUE READING
