Javier Cilleruelo, Thai Hoang Le
Motivated by a question of Sárközy, we study the gaps in the product sequence $\B=\A ... \A=\{b_n=a_ia_j, a_i,a_j\in \A\}$ when $\A$ has upper Banach density . We prove that t…

Green-Tao theorem in function fields
Thai Hoang Le
We adapt the proof of the Green-Tao theorem on arithmetic progressions in primes to the setting of polynomials over a finite field, to show that for every , the irreducible poly…
