## Abstract Let Ξ© be an open set in β^__N__^(__N__ β©Ύ 3), with compact boundary ΟΞ© of type __C__^1,Ξ±^(Ο΅(0,1)). We show that the single layer potential __Ef__, related to the stationary Stokes system on Ξ©, belongs to __C__^1,Ξ±^(ΟΞ©)^__N__^, provided the source density __f__ belongs to __C__^Ξ±^(ΟΞ©)^__N
## Abstract In this paper we consider the finite section method for the solution of the double layer potential equation corresponding to Laplace's equation in a threeβdimensional polyhedron. We prove the stability of our method in case of special polyhedrons.
