Comment on "Some novel delta-function identities"

Classical Physics 2015-05-14 v2

Abstract

We show that a form for the second partial derivative of 1/r1/r proposed by Frahm and subsequently used by other workers applies only when averaged over smooth functions. We use dyadic notation to derive a more general form without that restriction.
