Titel: A local to global principle for groups of Mordell-Weil type
Abstract: Let A be an abelian variety defined over a number field F.
I will discuss some Hasse principles for detecting linear
dependence of a given collection of nontorsion points of
A(F), via reductions at finite places of F. I'll start by
recalling a question of Erd{\" o}s on the integers, which
initiated this research.
