The ozone group of $U_{q}^{+} (B_{2})$

James Gómez, Helbert Venegas

We determine the ozone group of $U_q^{+}(B_2)$. More precisely, if $\ell=\operatorname{ord}(q^2)$ when $q$ is a root of unity, we obtain $$ \operatorname{Oz}(U_q^{+}(B_2)) \c…

The ozone groups of the algebras $B_{q} (f)$

James Gómez, Helbert Venegas

Let $q$ be a primitive $n$ -th root of unity, $n > 1$ , and let $f$ be a nonzero polynomial such that $n ∤ (j + 1)$ for every $j\in\supp(f)$. Set $e=\gcd(n,\{j+1:j\in\supp(f)\})$. We s…
