EIGENVALUE PROBLEMS FOR SINGULAR ODES
Donal O’Regan, Aleksandra Orpel · Glasgow Mathematical Journal · 2010
Abstract We investigate eigenvalue intervals for the Dirichlet problem when the nonlinearity may be singular at t = 0 or t = 1. Our approach is based on variational methods and cover both sublinear and superlinear cases. We also study the continuous dependence of solutions on functional parameters.
