Titre: Finiteness
theorems for atypical intersections
Resumé: Many
manifolds \(M\) come naturally with a distinguished
class of submanifolds exhibiting a special behaviour. Examples include
abelian varieties with sub-abelian varieties, locally homogeneous
spaces with totally geodesic sub-spaces, period domains with sub-period
domains, as well as strata of abelian differentials with affine
invariant submanifolds. Starting from the recent finiteness theorem of
Eskin-Filip-Wright, I will describe various related results (in the
different settings described above) and a new framework, based on
"Galois theory of foliations", that recovers most
of those works. The new approach is effective and it is a joint work
with D. Urbanik.
