On a Riemannian manifold of constant curvature, the Calabi operator is a second order linear differential operator that provides local integrability conditions for the range of the Killing operator. We generalise this operator to provide linear second order local integrability conditions on Riemannian locally symmetric spaces, whenever this is possible. Specifically, we show that this generalised operator always works in the irreducible case and we identify precisely those products for which it fails.

    The Riemannian deformation sequence is obtained as a BGG sequence from a flat connection on the adjoint tractor bundle, and identified with the deformation sequence of the Cartan connection.
