摘要:
This paper investigates the existence and uniqueness of positive solutions to a class of singular m-point boundary value problems of second order ordinary differential equations. A sufficient condition for the existence and uniqueness of C[0, 1] positive solutions as well as C-1[0, 1] positive solutions is given by constructing lower and upper solutions and with the maximal theorem. Our nonlinearity f(t, u) may be singular at u, t = 0 and/or t=1. (c) 2007 Elsevier Inc. All rights reserved.
