The author constructs fast direct solvers for the Poisson equation with homogeneous Dirichlet and Neumann boundary conditions on special triangles and tetrahedra. The construction is performed in such a way that the given domain is extended by symmetrization or skew symmetrization onto a rectangle or a rectangular parallelepiped, and a fast direct solver is used there. All extendable domains are found.
