Generalized hypergeometric $G$-functions take linear independent values
Abstract
In this article, we show a new general linear independence criterion related to values of -functions, including the linear independence of values at algebraic points of contiguous hypergeometric functions, which is not known before. Let be any algebraic number field and be a place of . Let with . Consider not being negative integers. Assume neither nor be strictly positive integers . Let with pairwise distinct. By choosing sufficiently large depending on and such that the points are closed enough to the origin, we prove that the numbers~ \begin{align*} &{}_{r}F_{r-1} \biggl(\begin{matrix} a_1,\ldots, a_r\\ b_1, \ldots, b_{r-1} \end{matrix} \biggm| \dfrac{\alpha_i}{\beta}\biggr)\enspace, \ \ {}_{r}F_{r-1} \biggl(\begin{matrix} a_1+1,\ldots,\ldots,\ldots,a_r+1\\ b_1+1, \ldots, b_{r-s}+1,b_{r-s+1},\ldots,b_{r-1} \end{matrix} \biggm| \dfrac{\alpha_i}{\beta}\biggr)\enspace\\ &(1\le i \le m, 1\le s \le r-1)\end{align*} and are linearly independent over . The essential ingredient is our term-wise formal construction of type II of Pad\'e approximants together with new non-vanishing argument for the generalized Wronskian.
