On the matrices with constant determinan
✍ S. Akbari; H.-R. Fanaı̈; K. Mahmoudian πŸ“‚ Article πŸ“… 2003 πŸ› Elsevier Science 🌐 English βš– 161 KB

Let Β΅ m be the group of mth roots of unity. In this paper it is shown that if m is a prime power, then the number of all square matrices (of any order) over Β΅ m with non-zero constant determinant or permanent is finite. If m is not a prime power, we construct an infinite family of matrices over Β΅ m

We consider various specializations of the untwisted quantum affine algebras at roots of unity. We define and study the q-characters of their finite-dimensional representations.
