On the average value of divisor sums in arithmetic progressions

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 ...

The Divisor Function in Arithmetic Progressions to Smooth Moduli

Abstract: By using the q-analog of van der Corput's method, we study the divisor function in an arithmetic progression to modulus q. We show that the expected asymptotic formula holds for a larger ...
