Manuel del Pino, Raul F Manasevich · Proceedings of the American Mathematical Society · 1991
We show existence for a nonlinear fourth-order boundary value problem under a nonresonance condition involving a two-parameter linear eigenvalue problem. We also state extensions of this result to certain higher-order P.D.E. cases.
