\(\mathcal H^2\)-matrix approximation of integral operators by interpolation
The authors study the solutions of the integral equation \[ \lambda u(x)+\int_\Gamma k(x,y)u(y)dy=f(x) \] for all \(x\in\Gamma\) for a right-hand side \(f\), a parameter \(\lambda\in\mathbb{R}\) and the kernel function \(k:\mathbb{R}^d\times\mathbb{R}^d\rightarrow\mathbb{R}\) that has asymptotic smoothness.
