Abstract

The classical Lehmer problem conjectures a lower bound for the Weil height of a non torsion element of ${\bf G}_m(\overline{\bf Q})$ in terms of the degree of its field of definition. Extensions of this problem to abelian varieties and more general multiplicative toruses have been studied over the last two decades. We shall discuss the general semi-abelian case.
