O'Regan, Donal
Existence theorems for certain classes of singular boundary value problems. (English)
[J] J. Math. Anal. Appl. 168, No.2, 523-539 (1992). ISSN 0022-247X

Using the method of a priori estimates and the nonlinear alternative of Leray-Schauder, the author proves some existence results for the nonlinear singular second order two-point BVP of the form $(1/p)$ $(py')'=f(t,y)/ \psi(t)$, $0<t<b$ with $y$ satisfying appropriate boundary conditions. Applications to Thomas-Fermi, singular Emden-Fowler and other special equations are given.
