Let and be the von Mangoldt function and M?bius function, respectively, x real and y“small” compared with x. This paper gives, for the first time, a non-trivial estimate of the sum
for all whenever . Correspondingly, it is also proved that
uniformly for all real α and any , and in the same range of y.

short intervals. 相似文献

Mathematical Notes - A new estimate of the Kloosterman sum with primes modulo a prime number q is obtained, in which the number of summands can be of order q0.5+ε. This estimate refines... 相似文献

Let J(N, H) be the Selberg integral and E(x, T) the error term in Kaczorowski-Perelli's weighted form of the classical explicit formula. We prove that the estimate J(N, H) = o(H2 N) is connected with an appropriate estimate of N

Goldston and Montgomery proved that the strong pair correlationconjecture and two second moments of primes in short intervalsare equivalent to each other under the Riemann hypothesis. Thepaper obtains the second main terms for each of the above, andit is shown that they are almost equivalent to each other. 相似文献
