Quasi-Monte Carlo methods for integration of functions with dominating mixed smoothness in arbitrary dimension

preprint2012arXivOpen access

Abstract

In a celebrated construction, Chen and Skriganov gave explicit examples of point sets achieving the best possible L2L_2-norm of the discrepancy function. We consider the discrepancy function of the Chen-Skriganov point sets in Besov spaces with dominating mixed smoothness and show that they also achieve the best possible rate in this setting. The proof uses a bb-adic generalization of the Haar system and corresponding characterizations of the Besov space norm. Results for further function spaces and integration errors are concluded.
