Maximal Nonparabolic Subgroups of the Modular Group
The elliptic elements of M, each with two conjugate complex fixed points, are precisely the conjugates of nontrivial powers of A and B. The parabolic elements, each with a single real fixed point, are precisely the conjugates of nontrivial powers of C = AB: z ~ z + 1. The remaining nontrivial elements of M are hyperbolic, each with two real fixed points. A subgroup S of M is torsionfree (and th...
متن کاملThe Mobius Function of Psl2(#), with Application to the Maximal Normal Subgroups of the Modular Group
This paper seeks to prove some results stated in [5], namely a statement of the Mobius function of PSL2(2 ), e > 1. These results extend P. Hall's calculation in [6] of the Mobius function of PSL2(/?) for any prime/?. The techniques used in the present paper (see especially §2) should be of use for evaluating the Mobius function fiG for other classical groups G; in fact for the case when G = ?S...
متن کاملComputing with subgroups of the modular group
We give several algorithms for finitely generated subgroups of the modular group PSL2(Z), given by sets of generators. First, we present an algorithm to check whether a finitely generated subgroup H has finite index in the full modular group. Then we discuss how to parametrise the right cosets of H in PSL2(Z), whether the index is finite or not. Further, we explain how an element in H can be wr...
متن کاملCongruence Subgroups of the Modular Group
The congruence subgroups of the classical modular group which can be defined as the automorphs modulo q of some fixed matrix are studied, and their genera determined. Let T = SL{2, Z). A congruence subgroup of T is any subgroup containing a principal congruence subgroup T^), defined as the set of elements A of T such that A = I mod q, where q is a positive integer. Of these one of the most impo...
متن کاملThe Modular Group A Finitely Generated Group with Interesting Subgroups
The action of Möbius transformations with real coefficients preserves the hyperbolic metric in the upper half-plane model of the hyperbolic plane. The modular group is an interesting group of hyperbolic isometries generated by two Möbius transformations, namely, an order-two element, g2 HzL = -1 ê z, and an element of infinite order, g• HzL = z + 1. Viewing the action of the group elements on a...
