On the exact order of the discrepancy of low discrepancy digital van der Corput--Kronecker sequences

Abstract: In this paper we give the exact order of the discrepancy of the digital van der Corput--Kronecker sequences that are based on recent counterexamples of the $X$-adic Littlewood conjecture in positive characteristics. Our result supports once again the well-established conjecture in the theory of uniform distribution which states that $D^*_N\leq c \frac{\log^s N}{N},\,c>0$ is the best possible upper bound for the star discrepancy $D^*_N$ of a sequence in $[0,1)^s$ or in other words for every sequence in $[0,1)^s$ $\limsup_{N\to\infty}ND^*_N/\log^s N>0$.
