00925njm 22002777a 4500 dc Bujalance, E. author Cirre, F.J. author Gamboa Mutuberria, José Manuel author 2024 We study large groups of automorphisms of compact orientable bordered Klein surfaces of topological genus one. Here, large means that the order of the group is greater than or equal to 4(g−1), where g ≥ 2 is the algebraic genus of the surface. We find all such groups, providing presentations by means of generators and relations of them. We also determine which of these groups act as the full automorphism group of some bordered torus.
