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.
