Abstract
Let B be the unit open ball in R(N) and u a positive solution of (E) : -Delta u + u(q) = 0, q > 1, in B. We prove that it is possible to def ine the trace of u on partial derivative B by a unique couple (S, mu) where S is a closed subset of partial derivative B and mu is a Radon m easure on R = partial derivative B\S. The set S is the singular set of the trace of a and the set R is the regular set where the trace of u is mu.
