The context is about sections of a pencil of tori or abelian varieties. Several results concern the set of parameters which destroy independence. We shall look at a generalization of this issue:
"For which parameters does a finitely generated group of sections meet a given subvariety?"
We shall discuss some joint results with Amoroso and Masser, for toric pencils: Under suitable assumptions we prove bounded height for the said parameters. There are diophantine applications.
