Bevan Thompson %J Electronic Journal of Differential Equations %D 2004 %I Texas State University %X It is well known that the classical linear Sturm-Liouville eigenvalue problem is self-adjoint and possesses a family of eigenfunctions which form an orthonormal basis for the space L_2. A natural question is to ask if a similar result holds for nonlinear problems. In the present paper, we examine the basis property for eigenfunctions of nonlinear Sturm-Liouville equations subject to general linear, separated boundary conditions. %K Sturm-Liouville operator %K basis property %K eigenfunction. %U http://ejde.math.txstate.edu/Volumes/2004/87/abstr.html
