A singular nonlinear boundary-value problem

Robert M. Houck & Stephen B. Robinson

Abstract:
In this paper we prove an existence and uniqueness theorem for the singular nonlinear boundary-value problem
$$\displaylines{
(|y'(t)|^py'(t))'+\frac{\phi}{y^{\lambda}(t)}=0 \hbox{ in } (0,1),\cr
y(0)=0=y(1),
}$$
where $p\geq 0$, $\lambda$ is a positive constant, and $\phi$ is a positive function in $L^1_{{\rm loc}}(0,1)$. Moreover, we derive asymptotic estimates describing the behavior of the solution and its derivative at the boundary.
