Symmetric Equilibria for a Beam with a Nonlinear Elastic FoundationM.R. Grossinho and T.F. MaFaculdade de Ciências - Universidade de Lisboa, Departamento de Matemática,Rua Ernesto de Vasconcelos, Bloco C1, 1700 Lisboa - PORTUGAL Centro de Matemática e Aplicaç\ oes Fundamentais, Avenida Prof. Gama Pinto, 2 - 1699 Lisboa Codex - PORTUGAL and Departamento de Matemática - Universidade Estadual de Maringá, Avenida Colombo, 3690, 87020 Maringá-PR - BRAZIL Abstract: We study the existence of symmetric solutions of a nonlinear fourth order O.D.E. with nonlinear boundary conditions arising in the theory of elastic beams. Variational methods are used, namely, duality, minimization and mountain pass. Full text of the article:
