Abstract.
We consider some problems in number theory which turn out to depend on various aspects of Kummer theory; among them are (1) does the assertion ``b is in the subgroup generated by a'' obey a local-global principle for points of an algebraic group over a number field; (2) if two abelian varieties have the same n-division fields for n≥1, what relation is there between them?
