In this paper we are interested in moments of the Minkowski question mark function
.
It appears that, to some extent, the results are analogous to results
obtained for objects associated with Maass wave forms: period functions,
-series,
distributions. These objects can be naturally defined for
as well. Various previous
investigations of
are mainly motivated from the perspective of metric number theory,
Hausdorff dimension, singularity and generalizations. In this work it is shown
that analytic and spectral properties of various integral transforms of
do
reveal significant information about the question mark function. We prove asymptotic
and structural results about the moments, calculate certain integrals which involve
,
define an associated zeta function, generating functions, Fourier series, and establish
intrinsic relations among these objects.
