In plate theory, the Kirchhoff-Love functional models the energy of a thin plate subject to an external force. Its critical points describe the deformation of the plate and turn out to be solutions of a linear fourth-order PDE in dimension 2 with Steklov boundary conditions. In this talk, we consider a generalization of this functional (which leads us to study a class of semilinear PDEs) and we investigate existence of positive least-energy solutions by variational methods. We also provide a convergence analysis for these solutions with respect to the parameter which appears in the boundary conditions. Webpage[
