i want to prove this equality:
http://img19.photobucket.com/albums/v57/tigor/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...[:)]
