Abstract in another language
A method for the kernel-independent construction of H²-matrix approximations to non-local operators is proposed. Special attention is paid to the adaptive construction of nested bases. As a side result, new error estimates for adaptive cross Approximation (ACA) are presented which have implications on the pivoting strategy of ACA.
