In this paper we derive second-order asymptotic results for matrices Matrices of the above form can be thought of as variable-coefficient Toeplitz matrices, or a discrete analogue of a pseudodifferential operator. Ideas from pseudodifferential operator theory are used in the proof.
During the last fifteen years it has become clear that local principles are a powerful tool in investigating FREDHO LM properties of singular integral operators and TOEPLITZ operators\*). We remind here only of the local methods of I. B. SIMONENKO [15], [lG], V. S. PILIDI [12], R. G. DOUGLAS [i] and
