This page contains data of deformations of so called Maass forms.
Before looking at the data it's wise to read
this for a
short explanation or this
preprint for a more thorough
explanation.

Each line in the datafiles corresponds to a Maass form on a particular
group. The data given is the spectral parameter giving the Laplace eigenvalue
and two parameters defining the group.
The first column in the textfiles
is the spectral
parameter R and the second and third are the parameters b and a respectively
defining the group. Follow any of the links above for an explanation of these
parameters.

Deformations of Maass forms related to Gamma_0(5):

Deformations of Maass forms related to Gamma_0(6):

Deformations of Maass forms (seemingly) not related to any arithmetic group:

In the files below are also Fourier coefficients to 5 examples of Maass forms
on nonarithmetic groups given. Each of these examples have slightly
larger R than in the examples above. The figure numbers refer to the paper
mentioned above.

Three nonarithmetic Maass forms with Fourier
coefficients from Figure 4.2.1.

Two odd Maass forms (with Fourier
coefficients) close to the avoided
crossing in Figure 4.4.2.
