More clearly, we will obtain higher order vertical and complete lifts of differentiable elements on complex manifold M to the extended complex manifold kM.

We investigate the existence and uniqueness of a classical solution and the existence of a periodic in time solution. In the Appendix, an existence result of periodic solutions for an auxiliary quasilinear parabolic equation is provided, together with a C0 estimate of such solution.
