| Title: | Groups commensurable with the modular group | Authors: | Lang, M.L. | Keywords: | Groups commensurable with PSL2 (Z) | Issue Date: | 15-Apr-2004 | Citation: | Lang, M.L. (2004-04-15). Groups commensurable with the modular group. Journal of Algebra 274 (2) : 804-821. ScholarBank@NUS Repository. https://doi.org/10.1016/S0021-8693(03)00421-6 | Abstract: | Let A and B be maximal subgroups of PSL2(ℝ) that commensurable with PSL2(ℤ) (S and T are commensurable with each other if S ∩ T is of finite index in both S and T). In this article, we determine the index [A: A ∩ B] and the level of A ∩ B (Appendix A). © 2004 Elsevier Inc.
