    sry i dont know how to type tensors with upper and lower indices. I can only show it by picture

    2. Relevant equations

    questions are in the picture

    3. The attempt at a solution

    I tried to read Geroch's "Geometrical Quantum Mechanics", (III Quantum Mechanics 14. Densities. Integrals. 15. States), but i still cannot understand it
