Casimir effect for the sphere revisited
arXiv:quant-ph/0206184 · doi:10.1016/S0375-9601(02)00895-2
Abstract
In a recent work Brevik \emph{et al.} have offered formal proofs of two results which figure prominently in calculations of the Casimir pressure on a sphere. It is shown by means of simple counterexamples that each of those proofs is necessarily incorrect.
