The authors investigate for a class of data-sparse recursive matrix representations of discretized integral operators (1) optimal linear complexity of the scheme, (2) an error analysis for integral operators of order zero, and (3) the optimal convergence which is retained for the classical double layer potential discretized with piecewise constant finite element functions.
