摘要
For second-order elliptic equations one usually extensively studies the case of Dirichlet boundary conditions and other boundary conditions are left to the reader. For the biharmonic equation Delta(2)u=f on a bounded domain in R-n it is not that obvious which boundary condition would serve as a role model. Usually a good approach is to focus on some boundary conditions which describe physically relevant situations. We will discuss boundary conditions for a slender beam and for the thin elastic plate.
