Abstract

Let Omega subset of R-2 be a bounded domain, and V epsilon C-0,C-1 (Omega) satisfy: 0 < a <= V <= b, vertical bar del V vertical bar <= A in Omega. For given alpha > 0 and 0 G Q, we show that every solution of the equation: -Delta u = vertical bar z vertical bar(2 alpha)Ve(u), in Omega satisfies: u (0) + infu(Omega) <= C, with a suitable constant C depending only on a, b, A and dist (0, delta Omega). This furnishes a nontrivial extension of an analogous result established by Brezis-Li-Shafrir in [3], in case alpha > 0.
