Elsevier Acta Medica Okayama 00224049 224 1 2020 Automorphism groups of rational surfaces 411 422 EN Takato Uehara Department of Mathematics, Okayama University In this paper, we consider automorphism groups of rational surfaces which admit cuspidal anticanonical curves and have certain nontrivial automorphisms. By applying Coxeter theory, we show that the automorphism groups of the surfaces are isomorphic to the infinite cyclic group. No potential conflict of interest relevant to this article was reported.
