Counting rational points on smooth cubic surfaces

TL;DR

This paper proves that smooth cubic surfaces over any number field meet the lower bound predicted by Manin's conjecture, possibly after a small degree extension, advancing understanding of rational points on algebraic surfaces.

Contribution

It establishes the Manin conjecture's lower bound for all smooth cubic surfaces over any number field, extending previous results.

Findings

Lower bound predicted by Manin's conjecture holds for all smooth cubic surfaces.

The result applies over any number field, possibly after a small extension.

Provides a significant step in understanding rational points on cubic surfaces.

Abstract

We prove that any smooth cubic surface defined over any number field satisfies the lower bound predicted by Manin's conjecture possibly after an extension of small degree.
