### On the radial derivative of the delta distribution

Fred Brackx UGent, Franciscus Sommen UGent and Jasson Vindas Diaz UGent (2017) 11(5). p.1035-1057
abstract
Possibilities for defining the radial derivative of the delta distribution $\delta(\ux)$ in the setting of spherical coordinates are explored. This leads to the introduction of a new class of continuous linear functionals similar to but different from the standard distributions. The radial derivative of $\delta(\ux)$ then belongs to that new class of so-called signumdistributions. It is shown that these signumdistributions obey easy-to-handle calculus rules which are in accordance with those for the standard distributions in $\mR^m$.
