We compute the dimensions of the components for the operad of two compatible brackets and for the bi-Hamiltonian operad. We also obtain character formulas for the representations of symmetric groups and $SL_2$ in these spaces.
Mots-clés : compatible Poisson brackets, Koszul operad
Keywords: distributive law, Cohen–Macaulay poset.
