CHARACTERIZATION OF A CYCLIC GROUP RING IN TERMS OF CHARACTER VALUES
Lee, Joongul;

Abstract
Let G be a cyclic group of prime power order. There is a natural embedding of $\small{\mathbb{Z}[G]}$ into a product of rings of integers of cyclotomic fields. In this paper the image of the embedding is determined, and we also compute the index of the image.
