Incompatible observables do not share a complete set of common eigenfunctions, because their operators do not commute.
It seems that, incompatible observables like x and p_x, S_x and S_y do not have any common eigenfunction at all.
Can anyone give a concrete example of a pair of incompatble observables that have common eigenfunctions but incomplete (do not span the Hilbert Space)?
