摘要
By use of the concavity of solution for an associate boundary value problem, existence criteria of positive solutions are given for the Dirichlet BVP[inline-graphic not available: see fulltext],[inline-graphic not available: see fulltext],[inline-graphic not available: see fulltext], where[inline-graphic not available: see fulltext] is odd and continuous with[inline-graphic not available: see fulltext],[inline-graphic not available: see fulltext], and[inline-graphic not available: see fulltext] may change sign and be singular along a curve in[inline-graphic not available: see fulltext].
