Abstract: | We have shown in 1]that the singular integral equation (1.2) on a closed surface Γ of R3 admits a unique solution q and is variational and coercive in the Hilbert space (Γ). In this paper, with the help of curved finite elements, we introduce an approximate surface Γh, and an approximate problem on Γh, whose solution is qh. Then we study the error of approximation |q ? qh| in some Hubert spaces and also the associated error |u ? uh| of the potential. |
