✦ Synopsis
We study the behavior near the origin of C 2 positive solutions u(x) of
in a punctured neighborhood of the origin in R n (n > 2) where the constants λ and a satisfy n n-2 < λ < n+2 n-2 and 0 < a < 1. We also study the existence of C 2 positive solutions of ( * ) in R n . In both cases we show that changing a from one value in the open interval (0, 1) to another value in (0, 1) can have a dramatic effect. 2002 Éditions scientifiques et médicales Elsevier SAS RÉSUMÉ. -On étudie le comportement prés de l' origine des solutions positives de classe C 2 u(x) de

## Abstract In this paper, we consider the semilinear elliptic problem where Ω⊂ℝ^N^ (__N__⩾3) is a bounded smooth domain such that 0∈Ω, σ>0 is a real parameter, $$\mu < \overline{\mu } = (N - 2)^{2} /4$$ and __f__(__x__) is some given function in L^∞^(Ω) such that __f__(__x__)⩾0, __f__(__x__)≢0 i
We consider the inequality u t ≥ u -1 2 x • ∇u + λu + h x t u p , for p > 1 λ ∈ , posed in N × + N ≥ 1. We show that, in certain growth conditions, there is an absence of global weak solutions.
