Examples for the standard conjecture of Hodge type

Abstract: For each prime number $p$ and each integer $g \geqslant 5$, we construct infinitely many abelian varieties of dimension $g$ over $\overline{\mathbb{F}}_p$ satisfying the standard conjecture of Hodge type. The main tool is a recent theorem of Ancona on certain rank $2$ motives. These varieties are constructed explicitly through Honda-Tate theory. Moreover, they have Tate classes that are not generated by divisors nor liftable to characteristic zero. Also, we prove a result towards a classification of simple abelian varieties for which the result of Ancona can be applied to. Along the way, we prove a result about Honda-Tate theory of independant interest.
