Title:Parallelogram inequality for abelian varieties and applications
Abstract:
Let $A$ be an abelian variety defined over a
number field. A theorem of Rémond states that for any two finite
subgroup schemes $G, H$, the Faltings height of the four isogenous
abelian varieties $A/G, A/H, A/(G+H), A/(G\cap H)$ are linked by an
elegant inequality, which has important applications in diophantine
geometry. The goal of the talk is to present an analogous inequality for
abelian varieties defined over function fields (in any characteristic).
This is joint work with Richard Griffon and Samuel Le Fourn.
