Conditional convergence of exponential sums related to a Hecke modular form
Definition
Consider the Fourier coefficients $\psi(n)$ of the modular form $\eta^4(6\tau)$,
which are defined in terms of $q=\exp(i2\pi\tau)$ by the identity:
$$\eta^4(6\tau) = q \prod_1^\infty (1-q^ …

Conditional convergence of exponential sums related to a Hecke modular form
Let me sum up my current state of knowledge.
First, here are some known facts about the coefficients $\psi(n)$ taken from the 1975 article by Ligozat called Courbes modulaires de genre 1.
Théorème B …
