abstract: In this talk, we consider an inverse source for an elliptic equation for which the source is a combiantion of monopolar and dipolar souces. Our problem is, first investigate identifiability question, then to study the stability issue and finally to establich an identification method to estimate the number, the locations and the moments of sources from boundary data.
On of the possible applications, but not the only one, of our study, could be the localization of the generators of electromagnetic fields in the head. The so-called inverse Electro-Encephalo-Graphy (EEG) problem.
