A remark on the existence of small solutions to a fourth order boundary value problem with large nonlinearity
Landesman-Lazer type problems at an eigenvalue of odd multiplicity
The aim of this paper is to establish some a priori bounds for solutions of Landesman-Lazer problem. We show the application for the solution structure of the nonlinear differential equation of the fourth order
On a fourth order periodic boundary value problem
Existence and uniqueness of the solution to a fourth order nonlinear vector periodic boundary value problem is proved by using the estimates for derivatives of the Green function for the corresponding homogenous scalar problem
