Prime number races and zeros of Dirichlet L-functions 09rit148
This Research in Teams meeting focused on the finer behaviour of the function π(x; q, a), which denotes the number of prime numbers of the form qn+ a that are less than or equal to x. Dirichlet’s famous theorem on primes in arithmetic progressions asserts that that there are infinitely many primes of the form qn + a when a is a reduced residue modulo q (that is, when a and q are relatively prim...
متن کاملPrime Number Races
There’s nothing quite like a day at the races . . . . The quickening of the pulse as the starter’s pistol sounds, the thrill when your favorite contestant speeds out into the lead (or the distress if another contestant dashes out ahead of yours), and the accompanying fear (or hope) that the leader might change. And what if the race is a marathon? Maybe one of the contestants will be far stronge...
متن کاملEffective multiplicity one on GLn and narrow zero-free regions for Rankin-Selberg L-functions
We establish zero-free regions tapering as an inverse power of the analytic conductor for Rankin-Selberg L-functions on GLn×GLn′ . Such zero-free regions are equivalent to commensurate lower bounds on the edge of the critical strip, and in the case of L(s, π × π̃), on the residue at s = 1. As an application we show that a cuspidal automorphic representation on GLn is determined by a finite numbe...
متن کاملA Standard Zero Free Region for Rankin Selberg L-functions
A standard zero free region is obtained for Rankin Selberg L-functions L(s, f×f) where f is a tempered Maass form on GL(n) and f is not necessarily self dual. The method is based on the theory of Eisenstein series generalizing a work of Sarnak. §
متن کاملNote on the Prime Number Theorem
Proof. First of all, we prove that if pn is the nth prime number then we have that pn ≤ 2 n−1 . Since there must be some pn+1 dividing the number p1p2 · · · pn− 1 and not exceeding it, it follows from the induction step that pn+1 ≤ 2 0 2 1 · · · 22n−1 = 220+21+···+2n−1 ≤ 22n . If x ≥ 2 is some real number, then we select the largest natural number n satisfying 22n−1 ≤ x, so that we have that 2 ...
