A virtually ample field that is not ample. (arXiv:1810.05184v1 [math.AG])
A field $K$ is called ample if for every geometrically integral $K$-variety
$V$ with a smooth $K$-point, $V(K)$ is Zariski-dense in $V$. A field $K$ is
virtually ample if some finite extension of $K$ is ample. We prove that there
exists a virtually ample field that is not ample.查看全文
