Give me please hint

  1. Mar 16, 2004 #1
    i want to prove this equality:

    dirac_lap.jpg

    it is trivial to show that it holds for all points outside small certain region around r=0
    in this case both sides of equality are 0

    i have a dificulty in proving the equality in region r~0

    so please give some hint how to attack this thing...:smile:
