Abstract

The aims of this paper are twofold. First, it discusses the Littlewood conjecture and its variants with respect to uniformly distributed sequences. The second aim is to determine the exact order of the discrepancy of the van der Corput--Kronecker-type sequences which are based on recent counterexamples to the X-adic Littlewood conjecture over a finite field. Our result on the exact order of the discrepancy supports the well-established conjecture in the theory of uniform distribution, which states that D_N≤ c (log^s N)/(N), with c>0 for all N>1 is the best possible upper bound for the discrepancy D_N of a sequence in [0,1)^s.
