Some applications of the large sieve in Riemann surfaces. (English) Zbl 0863.11062

We present some consequences of large sieve type inequalities related to the spectral analysis in a Riemann surface. We first prove some average results for the hyperbolic circle problem. For some special Fuchsian groups they imply average results for some arithmetical functions, for instance, for \(\sum_{k\leq n} r(k) r(k+ l)\) where \(r(k)\) is the number of representations as a sum of two squares or for the number of integral matrices with bounded entries leaving \(x^2- y^2- z^2\) invariant. We also show results relating the arithmetical character of the involved groups to spectral theory. Finally, a general large sieve inequality in compact manifolds is applied to get an average result for the off-centered (classical) circle problem and it is also applied in a physical context.
