Division quaternion algebras over some cyclotomic fields
Abstract
Let be two distinct prime integers, let be a positive integer, and let be a primitive root of order of the unity. In this paper we obtain a complete characterization for a quaternion algebra to be a division algebra over the th cyclotomic field , when and also we obtain a characterization for a quaternion algebra to be a division algebra over the th cyclotomic field , when . In the 4th section we obtain a complete characterization for a quaternion algebra to be a division algebra, when with a prime integer, (mod ) and a positive integer. In the last section of this article we obtain a complete characterization for a quaternion algebra to be a division algebra, when is a Fermat prime number.
