Vanishes identically

    What does it mean?

    the covariant derivative/ the torsion/ the eigenfunction...vanishes identically

    When and where does what vanish identically?

    "vanishes" means equal to 0. (I used to sit and wait for the "x" to vanish from the text book. It never did!)

    "Vanishes identically" means that the function is identically 0: 0 for all values of the variables.
