Computing sieve integrals using LattE, and the density of integers with a localized divisor

Sary Drappeau, Adrien Mounier

We consider the problem of estimating numerically integrals of the shape $\int_{P} \frac{d t}{t _{1} \dots t _{k}}$ where $P \in R_{> 0}^{k}$ is a convex polytope, $t=(t_1,\dots…

Central values of additive twists of MaaÃ forms $L$ -functions

Sary Drappeau, AsbjÃ¸rn Christian Nordentoft

In the present paper we study the central values of additive twists of MaaÃ forms $L$ -series. In the case of the modular group, we show that the additive twists (when averaged ove…

Exponential sums over integers without large prime divisors

Sary Drappeau, Igor E. Shparlinski

We obtain a new bound on exponential sums over integers without large prime divisors, improving that of Fouvry and Tenenbaum (1991). For a fixed integer $I^½ \neq = 0$ , we also obtain n…
