Abstract
AbstractA method for the kernel-independent construction of $$\mathcal {H}^2$$

-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.
