摘要
In this paper, we prove that for p > 1 the problem Delta u = a(x)u(p) in a bounded C-2 domain Omega of R-N has a unique positive solution with u = infinity on delta Omega. The nonnegative weight a(x) is continuous in (Omega) over bar but is only assumed to verify a " bounded oscillations" condition of local nature near delta Omega in contrast with previous works, where a definite behavior of a near delta Omega was imposed.
