## Abstract We obtain via Schauder's fixed point theorem new results for singular secondโ€order boundary value problems where our nonโ€linear term __f__(__t__,__y__,__z__) is allowed to change sign. In particular, our problem may be singular at __y__=0, __t__=0 and/or __t__=1. Copyright ยฉ 2002 John W

## Abstract We consider a singular anisotropic quasilinear problem with Dirichlet boundary condition and we establish two sufficient conditions for the uniqueness of the solution, provided such a solution exists. The proofs use elementary tools and they are based on a general comparison lemma combi
