We investigate arithmetic properties of values of the entire function F (z) = F q (z; λ) = ∞ n=0 z n n j=1 (q j − λ) , |q| > 1, λ / ∈ q Z>0 , that includes as special cases the Tschakaloff function (λ = 0) and the q-exponential function (λ = 1). In particular, we prove the non-quadraticity of the numbers F q (α; λ) for integral q, rational λ and α / ∈ −λq(More)
