Maximal subgroups of the modular and other groups
Maximal subgroups of the modular and other groups is a scholarly work, published in 2018 in ''Journal of Group Theory''. The main subjects of the publication include algebraic geometry, stock order, modular group, group, Fuchsian group, model theory, conjugacy class, combinatorics, mathematics, and finite group. The authors also extend results of Tretkoff and of Brenner and Lyndon for the modular group by constructing uncountably many conjugacy classes of such subgroups of Γ which do not arise from Neumann’s original method.
