Suppose $A$ is an abelian variety, $X, Y$ are subvarieties of $A$ of complementary dimension,

Does every component of $X \cap Y$ contribute positivelynon-negatively to the intersection number?

Suppose $A$ is an abelian variety, $X, Y$ are subvarieties of $A$ of complementary dimension,

Does every component of $X \cap Y$ contribute positively to the intersection number?

Intersection multiplicity in abelian varieties

Suppose $A$ is an abelian variety, $X, Y$ are subvarieties of $A$ of complementary dimension,

Does every component of $X \cap Y$ contribute positively to the intersection number?
