Cette Note porte sur une méthode algébrique permettant de résoudre un problème inverse de sources dans lʼéquation elliptique Δu+μu=F à partir dʼune seule donnée de Cauchy. Le terme source F est une fonction distribuée à support compact contenu dans un ensemble fini de sous-domaines de petites tailles.

This Note focuses on an algebraic reconstruction method allowing to solve an inverse source problem in the elliptic equation Δu+μu=F from a single Cauchy data. The source term F is a distributed function having compact support within a finite number of small subdomains.
