On Irregularity of Finite Sequences
Autor: S. V. Konyagin
Publikováno v: Proceedings of the Steklov Institute of Mathematics. 314:90-95
A sequence $$(x_1,x_2,\dots,x_{N+d})$$ of numbers in $$[0,1)$$ is said to be $$N$$ -regular with at most $$d$$ irregularities if for every $$n=1,\dots,N$$ each of the intervals $$[0,1),[1,2),\dots,[n-1,n)$$ contains at least one element of the sequen

On a symmetric Diophantine equation with reciprocals
Autor: S. V. Konyagin, M. A. Korolev
Publikováno v: Proceedings of the Steklov Institute of Mathematics. 294:67-77
An asymptotic formula is obtained for the number of solutions to a symmetric Diophantine equation with reciprocals, and its applications to problems related to the distribution of values of short Kloosterman sums are presented.

New results on sums and products in ℝ
Autor: I. D. Shkredov, S. V. Konyagin
Publikováno v: Proceedings of the Steklov Institute of Mathematics. 294:78-88
We improve previous sum–product estimates in ℝ; namely, we prove the inequality max{|A + A|, |AA|} ≫ |A|4/3+c, where c is any number less than 5/9813. New lower bounds for sums of sets with small product set are found. We also obtain results on

On some properties of finite sums of ridge functions defined on convex subsets of ℝ n
Autor: A. A. Kuleshov, S. V. Konyagin
Publikováno v: Proceedings of the Steklov Institute of Mathematics. 293:186-193
Necessary conditions are established for the continuity of finite sums of ridge functions defined on convex subsets E of the space R n . It is shown that under some constraints imposed on the summed functions ϕ i , in the case when E is open, the co
