摘要
This paper deals with the resolution of some inverse source problems in the 2D elliptic equation Delta u + mu u = F from Cauchy data. Two types of sources are considered, pointwise sources and sources having compact support within a finite number of small subdomains. An identification direct algorithm, based on an algebraic approach, is proposed. This is a new result, as far as we know, except in the case mu = 0 which is already considered in El Badia and Ha-Duong (2000 Inverse Problems 16 651-63).
