What notation would mathematicians use ?

  1. Jun 9, 2005 #1
    How would a mathematician write this:

    [tex]\hat{1} = \int dx |x\rangle \langle x| ?[/tex]

    This one,i guess

    [tex] \hat{1}=\int dx \ \hat{P}_{x} [/tex]

    ,where the projector acts on a rigged Hilbert space.

    As set of 4 spaces

    [tex] \Omega\subset\mathcal{H}\cong \tilde{\mathcal{H}}\subset \tilde{\Omega} [/tex]
