Weil numbers in finite extensions of ℚab: The Loxton-Kedlaya phenomenon

Florin Stan, Alexandru Zaharescu

Research output: Contribution to journalArticlepeer-review


A finiteness phenomenon described by Loxton and later by Kedlaya states that, for any fixed m, there exist (modulo multiplication by roots of unity) only finitely many m-Weil numbers in ℚab. In the present paper we show that this phenomenon extends to all finite extensions of ℚab.
