Detailed Description
template<typename T_ansatzsp, typename T_testsp>
class HLIB::TLaplaceSLPBF< T_ansatzsp, T_testsp >
TLaplaceSLPBF implements the bilinear form for the Laplace single layer potential with the kernel function
![\[ \frac{1}{\|x-y\|_2} \]](form_43.png)
i.e. for the integral equation
![\[ 4 \pi \int_{\Gamma} \frac{u(y)}{\|x-y\|_2} dy = f(x) \]](form_44.png)
