We present a spectral method for solving elliptic equations which arise in general relativity, namely three-dimensional scalar Poisson equations, as well as generalized vectorial Poisson equations of the type N + Ξ» β( β β’ N) = S with Ξ» = -1. The source can extend in all the Euclidean space R 3 , pro
## A priori estimate a b s t r a c t We propose a stabilized finite element method for the approximation of the biharmonic equation with a clamped boundary condition. The mixed formulation of the biharmonic equation is obtained by introducing the gradient of the solution and a Lagrange multiplier
