## Abstract We obtain via Schauder's fixed point theorem new results for singular second‐order boundary value problems where our non‐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 © 2002 John W
