Remark on Laquer's theorem for circulant determinants

Document Type : Research Paper


Faculty of Education, University of Miyazaki, Miyazaki, Japan


Olga Taussky-Todd suggested the problem of determining the possible values of integer circulant determinants. To solve a special case of the problem, Laquer gave a factorization of circulant determinants. In this paper, we give a modest generalization of Laquer's theorem. Also, we give an application of the generalization to integer group determinants.
