EXPONENTIAL SUMS OVER PRIMES IN SHORT INTERVALS AND AN APPLICATION TO THE WARING–GOLDBACH PROBLEM [PDF]

open access: yesMathematika, 2016
Let $ (n)$ be the von Mangoldt function, $x$ real and $2\leq y \leq x$. This paper improves the estimate on the exponential sum over primes in short intervals \[ S_k(x,y; ) = \sum_{x< n \leq x+y} (n) e\left( n^k \right) \] when $k\geq 3$ for $ $ in the minor arcs.

The twin prime conjecture [PDF]

open access: yes, 2014
This is an exposition of recent developments in the theory of bounded differences between primes. Readers are expected to be beginners of analytic number theory.

Estimates for the number of sums and products and for exponential sums over subgroups in fields of prime order

open access: yesComptes Rendus. Mathématique, 2003
Our first result is a ‘sum–product’ theorem for subsets A of the finite field 𝔽 p , p prime, providing a lower bound on max(|A+A|,|A·A|). As corollary, the second and main result provides new bounds on exponential sums associated to subgroups of the multiplicative group 𝔽 p * .

Exponential sums over primes are unbounded

open access: yes
We prove prime exponential sums have no better than square root cancellation on average on short intervals, in the sense that $$\frac{1}{x} \sum_{-y< n\le x} \left|\sum_{\substack{n< m \le n+y\\ 1\le m \le x}} Λ(m) \mathrm{e}(αm)\right|^2 \gg y\log y$$ whenever $y \ll x^{1/3-\varepsilon}.$ This answers a question of Ramaré by proving the lower ...

Value distribution for eigenfunctions of desymmetrized quantum maps

open access: yes, 2001
We study the value distribution and extreme values of eigenfunctions for the ``quantized cat map''. This is the quantization of a hyperbolic linear map of the torus. In a previous paper it was observed that there are quantum symmetries of the quantum map
