We study the existence of multiple solutions for a class of even-order nonlinear elliptic equations with the Dirichlet boundary conditions. We also study the corresponding nonlinear Hamiltonian system of higher-order linear equations.
Keywords: higher-order elliptic equation, convex-concave nonlinearity, fibering method, variational method, Hamiltonian system, Dirichlet problem.
