Roth's Theorem in Super Smooth Numbers

Number Theory 2025-10-22 v1

Abstract

We say that the set of yy-smooth numbers S(N,y)\mathcal{S}(N,y) up to NN is super smooth if y=logKNy=\log^KN for a large fixed constant KK. We show that the Roth's theorem on arithmetic progressions is true in super smooth numbers case. This extends the result of Harper where he showed the statement is true under a weaker hypothesis.
