Γ WebFeb 22, 2014 · If (a b c d) ∈ SL2(R) normalizes SL2(Z), then it also normalizes the Z -span of SL2(Z), which is the full ring of integer two by two matrices. Thus one finds that a2, ab, ac, ad, b2, bc, bd, c2 , cd, d2 are all integers. As explained by Igor this means that there are integers x, y, z, w, t, t ≥ 0 so that a = x√t, b = y√t, c = z√t, d = w√t.

Web3 Answers Sorted by: 11 Certainly S L ( 2, Z) contains a free group. For instance Γ ( 2), the subgroup of all matrices congruent to the identity modulo 2, is free of rank 2. The matrices ( 1 2 0 1) and ( 1 0 2 1) freely generate Γ ( 2). This can be proved by considering the action on the upper half-plane or by careful examination of reduced words. WebKeith Conrad has a lovely set of notes on this. This commutator subgroup is isomorphic to the free non-abelian group of rank 2. It is known that the commutator subgroup of a free group of rank >1 is free of infinite rank. In particular, for the free group of rank 2, is free on the set .

WebTake for example G = H m where H = A n and n! / 8 < m < n! / 4. For m = n! / 8 and n large enough, d ( G) = 2, while for m = n! / 4, d ( G) = 3. Computing where exactly the transition happens involves computing Möbius inversion of the whole subgroup lattice of H. This is, clearly, a Herculean task in practice if not in theory.
