Résumé : We discuss existence and multiplicity of positive solutions of the one-dimensional prescribed curvature problem- (u′ / sqrt(1 + u′ 2))′ = λ f (t, u), u (0) = 0, u (1) = 0, depending on the behaviour at the origin and at infinity of the potential ∫0 u f (t, s) d s. Besides solutions in W2, 1 (0, 1), we also consider solutions in Wloc 2, 1 (0, 1) which are possibly discontinuous at the endpoints of [0, 1]. Our approach is essentially variational and is based on a regularization of the action functional associated with the curvature problem. © 2007 Elsevier Inc. All rights reserved.
