Boundary Value Problems volume 2009, Article number: 103867 (2009)
Abstract
This paper studies the eigenvalue interval for the singular boundary value problem , where may be singular at , , and may change sign and be superlinear at . The approach is based on an approximation method together with the theory of upper and lower solutions.
