摘要

We consider the following the p-Laplacian equation in a boundeddomain f-Apu = f (x, u) in 11, u = 0on aci. We treat the case of nonlinearity term f satisfying the following conditionsaot11:1 - botP14 o(ltiP-1) f (x,t) =- btP_-' + o(ItiP-1) for constants ao, b0, a and b. We prove the existence of a positive solution or anegative solution in the case of (ao - Ai)(a - A1) = 0 or (bo - A1)(b - A1) = 0respectively, where A1 is the first eigenvalue of -Op.
