Irreducibility of the Cayley-Menger determinant, and of a class of related polynomials

Mowaffaq Hajja, Mostafa Hayajneh, Bach Nguyen +1

If $S$ is a given regular $n$ -simplex, $n \geq 2$ , of edge length $a$ , then the distances $a_{1}$ , $\dots$ , $a_{n + 1}$ of an arbitrary point in its affine hull to its vertices are rel…

Conjugacy classes and invariant subrings of R-automorphisms of R[x]

Jebrel M. Habeb, Mowaffaq Hajja, William J. Heinzer

We consider the group G of R-automorphisms of the polynomial ring R[x] especially in the case where R is the ring of integers modulo n. We describe conjugacy classes in G, and in t…
