On the $v$-adic values of G-functions III

Abstract

In this third part in this series we continue from \cite{papaspadicpart1}, the study of relations among values of G-functions associated to a $1$-parameter family of principally polarized abelian surfaces. In particular, we establish relations among the values of these G-functions, in both the archimedean and $p$-adic setting, at points corresponding to abelian surfaces with Quaternionic multiplication. We also discuss applications to the Zilber-Pink conjecture in $\mathcal{A}_2$ that naturally follow from our discussion.
