Streszczenie
We obtain nontrivial upper bounds on bilinear sums of Gauss sums modulo a prime. Our argument is based on a bound of J. Bourgain and M. Z. Garaev (2014) on the additive energy of modular reciprocals and on recent bounds on the additive energy of modular square roots due to A. Dunn, B. Kerr, I. D. Shkredov, I. E. Shparlinski and A. Zaharescu (2020–2021).
