An upper and lower solution theory is presented for singular initial value problems. Our non-linear term may be singular in both the independent and dependent variable. Existence will be established using Schauder's "xed point theorem and the Arzela}Ascoli theorem.

The singular boundary value problem is studied in this paper.The singularity may appear at t = 0 and the function g may be superlinear at u = โˆž and change sign. The existence of solutions is obtained via an upper and lower solutions method.
