A subexponential upper bound for van der Waerden numbers W(3,k)

Tomasz Schoen

We show an improved upper estimate for van der Waerden number $W (3, k) :$ there is an absolute constant $c > 0$ such that if ${1, \dots, N} = X \cup Y$ is a partition such that $X$ does n…

Improved bound in Roth's theorem on arithmetic progressions

Tomasz Schoen

We prove that if $A \subseteq {1, \dots, N}$ does not contain any non-trivial three-term arithmetic progression, then $∣ A ∣ ≪ \frac{( lo g lo g N ) ^{3 + o (1)}}{lo g N} N .$

Character sums estimates and an application to a problem of Balog

Tomasz Schoen, Ilya D. Shkredov

We prove new bounds for sums of multiplicative characters over sums of set with small doubling and applying this result we break the square--root barrier in a problem of Balog conc…
