The paper considers the natural problem whether, given a rational point on an algebraic group, the local divisibility by n implies that point is rationally divisible by n. Some significant cases are completely settled (e.g. elliptic curves) and other results are presented.

Abstract

The paper considers the natural problem whether, given a rational point on an algebraic group, the local divisibility by n implies that point is rationally divisible by n. Some significant cases are completely settled (e.g. elliptic curves) and other results are presented.
