Bounded height in pencils of finitely generated subgroups

Date: October 17, 2019 | 1:30 pm – 3:30 pm
Speaker: Umberto Zannier, Scuola Normale Superiore, Italy
Location: Heinzel Seminar Room / Office Bldg West (I21.EG.101)

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.
