摘要：
The singular boundary value problem [GRAPHICS] is studied in this paper. The singularity may appear at t = 0 and the function g may be superlinear at it = infinity and change sign. The existence of solutions is obtained via an upper and lower solutions method. (c) 2008 Elsevier Ltd. All rights reserved.
