A virtually ample field that is not ample

Abstract

A field KK is called ample if for every geometrically integral KK-variety VV with a smooth KK-point, V(K)V(K) is Zariski-dense in VV. A field KK is virtually ample if some finite extension of KK is ample. We prove that there exists a virtually ample field that is not ample.
