## Abstract We examine the numerical approximation of the integral equation (ฮป โ __K__)__u__ =__f__, where __K__ is the double layer (harmonic) potential operator on a closed polyhedral surface in โ^3^ and ฮป, โฃฮปโฃโฅ1, is a complex constant. The solution is approximated by Galerkin's method, which is
