论文摘要
如果a和b是一个数字k上的阿贝尔品种，因此大多数k的大多数a和b的降低a和b之间存在非平凡的几何同态，那么存在非k. b的非平地（几何）同质（几何）同质性。
If A and B are abelian varieties over a number field K such that there are non-trivial geometric homomorphisms of abelian varieties between reductions of A and B at most primes of K, then there exists a non-trivial (geometric) homomorphism from A to B defined over an algebraic closure of K.
