Constructing an automorphic form from the orbit of a transformation

Abstract:
We consider the Fuchsian groups of linear-fractional transformations. We propose a new method for presenting automorphic forms as gap series over an appropriate subset of transformations of the group which is not a subgroup. Comparative analysis of the Poincaré theta-series and gap series demonstrates that the use of gap series requires less transformations and parameters that the summands of series depend on.
Keywords:
Fuchsian group of linear-fractional transformations, Poincaré theta-series.
