Let ? denote a smooth, bounded domain in RN(N≥2). Suppose that g is a nondecreasing C1 positive function and assume that b(x) is continuous and nonnegative in?, and that it may be singular on ??. In this paper, we provide sufficient and necessary conditions on the existence of boundary blow-up solutions to the p-Laplacian problem ?pu = b(x)g(u) for x∈?, u(x)→+∞ as dist(x, ??)→0.The estimates of such solutions are also investigated. Moreover, when b has strong sin... 相似文献
