Aug 27, 2014 at 14:57 comment added anon By the Tate conjecture, I mean the equivalent statements of 2.9 of Tate's Seattle article (the order of the pole of the zeta function is equal to the rank of a certain group of algebraic classes). This implies that numerical equivalence equals homological equivalence (ibid.). The Lefschetz standard conjecture says that a certain map of spaces of algebraic cycles is an isomorphism. The Tate conjecture (in the above form) implies that it becomes an isomorphism when tensored with $\mathbb{Q}_l$.

Aug 24, 2014 at 17:15 comment added abx What about the Lefschetz type conjecture, and the comparison between numerical and homological equivalence?
