P. Habets et L. Sanchez, A 2-POINT PROBLEM WITH NONLINEARITY DEPENDING ONLY ON THE DERIVATIVE, SIAM journal on mathematical analysis, 28(5), 1997, pp. 1205-1211
We study the existence and multiplicity of solutions for a two-point b
oundary value problem at resonance in the first eigenvalue; the nonlin
earity depends only on the first derivative and has finite limits at /- infinity.
