I am a postdoc of Uwe Jannsen interested in arithmetic geometry, especially Arithmetic of Abelian schemes, their $L$-functions and étale cohomology.

comment commutative diagram with Yoneda pairing, Weil pairing and edge morphism
Thank you very much. I tried to fix the first diagram accordingly, but on the left, there should by two vertical arrows pointing down and up, respectively.

comment Poincaré bundle and Weil pairing for Abelian schemes
The normalised Poincaré bundle is $\mathscr{P} \otimes f_{A^\vee}^*g_{A^\vee}^*\mathscr{P}$ with $f: A \to X$ and $g$ the zero section.
