Abstract:	In this paper we ascertain the singular point-wise behavior of the positive solutions of a semilinear elliptic boundary value problem (1) at the critical value of the parameter, λ, where it begins its metasolution regime. As the weight function m(x) changes sign in ", our result is a substantial extension of a previous, very recent, result of Li et al. [8], where it was imposed the (very strong) condition that m ≥ 0 on a neighborhood of b−1({0}). In this paper, we are simply assuming that m(x0) > 0 for some x0 ∈ b−1({0}).
