Rational approximation on cubic hypersurfaces

Algebraic Geometry 2023-10-04 v1 Number Theory

Abstract

We compute the constant of approximation for an arbitrary rational point on an arbitrary smooth cubic hypersurface XX over a number field kk, provided that there is a kk-rational line somewhere on XX. In the process, we verify the Coba conjecture for XX.
