WebAfter a good deal of development, this inequality reached the elegant form?(x; q, a)< 2 1&; x,(q) log x (1.3) where x˚2 and;= log q log x <1. (1.4) See Montgomery and Vaughan [14]. … Webwhen using the approach we already put to work for the coset Brun-Titchmarsh inequality in [14]. The surprise is that, though we seem to be using the same kind of sieve argument as when bounding the density from above, the additive consequences are distinct. The additive combinatorial problem that emerges is investigated in Section 4.
WebJan 1, 1978 · Next chapter. Chapter XV The Titchmarsh Theorem About 50 years ago, E. C. Titchmarsh discovered, by the occasion of investigating zeros of some analytical functions, an interesting theorem on convolution. That theorem plays an important role in modern Analysis and is actually called the Titchmarsh Conuolution Theorem. WebThe main surprise is that we use sieve techniques in the form of Brun-Titchmarsh inequality but we are not blocked by the parity principle. The reader may argue that we use a lower bound for L(1,χ), but the bound we employ is the weakest possible and does not rely on Siegel’s Theorem. In particular, it is not strong

See more Let $${\displaystyle \pi (x;q,a)}$$ count the number of primes p congruent to a modulo q with p ≤ x. Then $${\displaystyle \pi (x;q,a)\leq {2x \over \varphi (q)\log(x/q)}}$$ for all q < x. See more By contrast, Dirichlet's theorem on arithmetic progressions gives an asymptotic result, which may be expressed in the form but this can only be proved to hold for the more restricted … See more The result was proven by sieve methods by Montgomery and Vaughan; an earlier result of Brun and Titchmarsh obtained a weaker version of … See more If q is relatively small, e.g., $${\displaystyle q\leq x^{9/20}}$$, then there exists a better bound: $${\displaystyle \pi (x;q,a)\leq {(2+o(1))x \over \varphi (q)\log(x/q^{3/8})}}$$ This is due to Y. Motohashi (1973). He used a bilinear … See more
