Abstract
The space of all tensor fields on , equipped with the Schouten bracket is a Lie algebra. The subspace of ascending tensors is a Lie subalgebra of . In this paper, we compute the cohomology of the adjoint representations of this algebra (in itself and ), when we restrict ourselves to cochains defined by aerial Kontsevitch's graphs like in our previous work (Pacific J of Math, vol 229, no 2, (2007) 257-292). As in the vectorial graphs case, the cohomology is freely generated by all the products of odd wheels.
