# Integral and series representations of the dirac delta function

@article{Li2007IntegralAS, title={Integral and series representations of the dirac delta function}, author={You Tang Li and Roderick S. C. Wong}, journal={Communications on Pure and Applied Analysis}, year={2007}, volume={7}, pages={229-247} }

Mathematical justifications are given for several integral and
series representations of the Dirac delta function which appear in
the physics literature. These include integrals of products of
Airy functions, and of Coulomb wave functions; they also include
series of products of Laguerre polynomials and of spherical
harmonics. The methods used are essentially based on the
asymptotic behavior of these special functions.
