Abstract:A correct formulation of the Lion-Rolin Preparation Theorem for logarithmic -subanalytic functions (LA-functions) is given. In [2] Lion and Rolin give an explicit description of functions on R n (n ∈ Z, n > 0), called by them LE-functions, defined as finite compositions of globally subanalytic functions with logarithmic and with exponential functions. This enables them to obtain the fundamental results of van den Dries, Macintyre and Marker [1] without making use of model theory. One important step in their st… Show more

“…The first three A 1 (q), A 3 (q), and A 5 (q) with q = x 1/2 define the Ramanujan functions P (x), Q(x), and R(x), respectively. Applying Nesterenko's theorem, we derived the following theorem [7,Theorem 2]: For any algebraic number α with 0 < |α| < 1, the numbers A 1 (α), A 2i+1 (α), and A 2j +1 (α) with 1 ≤ i < j and (i, j ) = (1, 3) are algebraically independent over Q. Furthermore, A 7 (q) = A 3 (q) + 120A 3 (q) 2 as q-series.…”
The sixteen families of q-series containing the Ramanujan functions were listed by I.J. Zucker (SIAM J. Math. Anal. 10:192-206, 1979), which are generated from the Fourier series expansions of the Jacobian elliptic functions or some of their squares. This paper discusses algebraic independence properties for these q-series. We determine all the sets of q-series such that, at each algebraic point, the values of the q-series in the set are algebraically independent over Q. We also present several algebraic relations over Q for two or three of these q-series.
