• Character Sums over Integers with Restricted g-ary Digits 

    Banks, William David, 1964-; Conflitti, Alessandro; Shparlinski, Igor E. (2002)
    We establish upper bounds for multiplicative character sums and exponential sums over sets of integers that are described by various properties of their digits in a fixed base g ≥ 2. Our main tools are the Weil and ...
