TITLE: Cyclic p-roots of prime length
ABSTRACT: We present a result of U. Haagerup, proved independently by T. Tao, stating that for every p prime there exist only finitely many cyclic p-roots. This is equivalent to saying that there are finitely many non-equivalent cyclic Hadamard matrices of prime dimension.
