Generalized Quaternion Rings over $\mathbb{Z}/n\mathbb{Z}$ for an odd $n$

J. M. Grau, C. Miguel, A. M. oller-Marcén

We consider a generalization of the quaternion ring $\left(\frac{a,b}{R}\right)$ over a commutative unital ring $R$ that includes the case when $a$ and $b$ are not units of $R$. In th…
