On Double Sums with Multiplicative Characters
On Double Sums with Multiplicative Characters is a scholarly work, published in 2018 in ''Mathematical Notes''. The main subjects of the publication include pure mathematics, arithmetic, graph theory, multiplicative function, combinatorics, mathematics, prime number theorem, and Quasi-Monte Carlo method. An estimate for double sums of multiplicative characters with additive convolutions of the characteristic functions of sets having small additive doubling is obtained.
