Title: On the average value of divisor sums in arithmetic progressions
Author: Banks, William David, 1964-; Heath-Brown, D. R.; Shparlinski, Igor E.
Date: 0000
Abstract: We consider very short sums of the divisor function in arithmetic progressions prime to a fixed modulus and show that "on average" these sums are close to the expected value. We also give applications of our result to sums of the divisor function twisted with characters (both additive and multiplicative) taken on the values of various functions, such as rational and exponential functions; in particular, we obtain upper bounds for such twisted sums.
