The Selberg-Delange method in short intervals with some applications
- 57 Downloads
In this paper, we establish a quite general mean value result of arithmetic functions over short intervals with the Selberg-Delange method and give some applications. In particular, we generalize Selberg’s result on the distribution of integers with a given number of prime factors and Deshouillers-Dress-Tenenbaum’s arcsin law on divisors to the short interval case.
