An
introduction to both the geometry and the arithmetic of abelian varieties. It
includes a discussion of the theorems of Honda and Tate concerning abelian
varieties over finite fields and the paper of Faltings in which he proves
Mordell's Conjecture. Warning: These notes are less polished than the others.
