Next, we study the bi-Laplacian and associated equations: the iterated Poisson equation, the bi-Laplace Neumann and Dirichlet problems, and the "plate equation". It turns out that the bi-Laplace Dirichlet to Neumann map is of non-trivial interest. The exposition concludes with two detailed ...

As the main problem, the bi-Laplace equation, being a model from fracture mechanics/elasticity, $\D^2 u=0 \quad (\D=D_x^2+D_y^2)$ in a bounded domain $\O \subset e^2$, with inhomogeneous Dirichlet or Navier-type conditions on the smooth boundary $\p \O$ is considered. In ...

On any bounded domain the Dirichlet or Neumann–Laplace operator has a first eigenfunction which is the unique one of fixed sign. For the bilaplace operator, as for any fourth order operator, there is no direct maximum principle and hence no obvious argument for a first eigenfunction of one ...
