A result on the Galois theory of q-difference equations (Sauloy in Théorie analytique locale des équations aux q-différences de pentes arbitraires. See arXiv:2006.03237v1, 2020) leads to the following question: If q ∈ C * ...

See arXiv:2006.03237v1, 2020) leads to the following question: If q ∈ C * , |q| < 1 and if one sets θ q (z) := m∈Z q m(m-1)/2 z m , can some coefficients of the Laurent series expansion of θ k q (z), k ∈ N * , vanish ? We give a partial answer.Show less >
