Abstract

Let A=A(E,σ)A=\mathcal{A}(E,\sigma) be a 33-dimensional quantum polynomial algebra where EE is P2\mathbb{P}^{2} or a cubic divisor in P2\mathbb{P}^{2}, and σAutkE\sigma\in \mathrm{Aut}_{k}E. Artin-Tate-Van den Bergh proved that AA is finite over its center if and only if the order σ|\sigma| of σ\sigma is finite. As a categorical analogy of their result, the author and Mori showed that the following conditions are equivalent; (1) νσ3<|\nu^{\ast}\sigma^{3}|<\infty, where ν\nu is the Nakayama automorphism of AA. (2) The norm σ\|\sigma\| of σ\sigma is finite. (3) The quantum projective plane ProjncA\mathsf{Proj}_{{\rm nc}}A is finite over its center. In this paper, we will prove for Type S' algebra AA that the following conditions are equivalent; (1) ProjncA\mathsf{Proj}_{{\rm nc}}A is finite over its center. (2) The Beilinson algebra A\nabla A of AA is 22-representation tame. (3) The isomorphism classes of simple 22-regular modules over A\nabla A are parametrized by P2\mathbb{P}^{2}.
