The graded Lie algebra L associated to the Nottingham group is a loop algebra Γ΄f the Witt algebra W . The universal covering W of W has one-dimensional 1 1 1 Δentre, so that the corresponding loop algebra M of W has an infinite-dimen-1 Ε½ . Ε½ . sional centre Z M .

The aim of this paper is to determine the first three spaces of weight -1 of the adjoint cohomology of the Nijenhuis-Richardson algebra of the functions of a manifold, which are important in deformation theory (the first and second will be computed for an arbitrary weight q β€ -1).
