✦ Synopsis

Describing ionic transport through regions where there is a non-zero space charge density by using the Nernst-Planck and Poisson equations involves some conceptual and mathematical diEiculties. In the present paper, the significance of the electroneutratity assumption and the potential difference derived from it, as well as the applicability conditions making this hypothesis valid, are discussed.

This work presents a new recursion scheme to compute the cartesian derivatives of potentials on the smooth surface of a connected solid. The advocated strategy solely appeals to boundary-integral equations and a very few informations regarding the surface geometry. The whole algorithm is carefully t
