Integral over an operator

  1. Sep 22, 2008 #1
    since in QM we deal with noncommutative operators , for example

    [tex] [A,B]=i\hbar 1 [/tex]

    then my question is if we could define some kind of noncommutative integral

    [tex] \int dA dB exp(-iAB) [/tex] here A and B would be operators

    how can you define for an operator a 'measure' [tex] dA [/tex]

    In general one never integrates over operators in QM.
