    Hi drFredkin. Welcome to the forum.

    A little context might help. What do you mean "compatible operator?" Since you did not write down "compatible operators equation" it is hard to guess what you want.

    They are certainly "compatible" in the sense that they commute and can be simultaneously diagonalized...
