%0 Journal Article %T $L_2$ discrepancy of linearly digit scrambled Zaremba point sets %A Henri Faure %A Friedrich Pillichshammer %A Gottlieb Pirsic %J Uniform Distribution Theory %D 2011 %I Mathematical Institute of the Slovak Academy of Sciences %X We give an exact formula for the $L_2$ discrepancyof a class of generalized two-dimensional Hammersley point sets in base $b$, namely generalized Zaremba point sets.For the construction of such point sets one needs sequences of permutations of the form $\pi_l(k)=\alpha k +l \pmod{b}$ for $k,l \in {0,\ldots,b-1}$. As a corollary we obtain a condition on these sequences which yields the best possible order of $L_2$ discrepancy of generalized Zaremba point sets in the sense of Roth's lower bound, with very small leading constants. %K $L_2$ discrepancy %K generalized Hammersley point set %K linear digit scrambling %U http://www.boku.ac.at/MATH/udt/vol06/no2/05%20FPP.pdf
