摘要
This paper studies the existence of solutions to the singular boundary value problem [GRAPHICS] where g: (0, 1) X (0, infinity) -> R and h: (0, 1) x [0, infinity) -> [0, infinity) are continuous. So our nonlinearity may be singular at t = 0, 1 and u = 0 and, moreover, may change sign. The approach is based on an approximation method together with the theory of upper and lower solutions.
