Series constructor for modular forms for Hecke triangle groups

AUTHORS:

  • Based on the thesis of John Garrett Leo (2008)
  • Jonas Jermann (2013): initial version

Note

J_inv_ZZ is the main function used to determine all Fourier expansions.

Constructor for the Fourier expansion of some (specific, basic) modular forms.

The constructor is used by forms elements in case their Fourier expansion is needed or requested.
