Abstract
We investigate the class of all positive solutions of the equation Lu = u(alpha), 1 < alpha less than or equal to 2 in a smooth domain E sub set of R-d. We define the fine trace tr(u) of a solution u as a pair ( Gamma, nu), where Gamma is a set of singular boundary points of u, and nu is a certain sigma-finite measure on the complement of Gamma. We d escribe all possible traces and we construct the minimal solution with the given trace. (C) Academie des Sciences/Elsevier, Paris.
