On modular forms for some noncongruence subgroups of SL_2(Z) II
Ling Long, Chris Kurth
In this paper we show two classes of noncongruence subgroups satisfy the so-called unbounded denominator property. In particular, we establish our conjecture in [KL08] which says t…

Computations with finite index subgroups of using Farey Symbols
Chris A. Kurth, Ling Long
Finite index subgroups of the modular group are of great arithmetic importance. Farey symbols, introduced by Ravi Kulkarni in 1991, are a tool for working with these groups. Given…

On modular forms for some noncongruence arithmetic subgroups
Chris Kurth, Ling Long
In this paper, we consider modular forms for finite index subgroups of the modular group whose Fourier coefficients are algebraic. It is well-known that the Fourier coefficients of…
