The integral Tate conjecture over finite fields and two coniveau filtrations
鈴木文顕 氏 (北京大学)
The integral Tate conjecture over finite fields and two coniveau filtrations
[ 講演概要 ]
We construct a new type of counterexamples to the integral Tate conjecture over finite fields, where a geometric cycle map is surjective but an arithmetic cycle map is not. We also discuss the relation of this problem with two coniveau filtrations, and show some positive results toward a conjecture of Colliot-Thélène and Kahn. This is joint work with Federico Scavia.
