Abstract

We prove new linear independence results for the values of generalized hypergeometric functions pFq{}_pF_q at several distinct algebraic points, over arbitrary algebraic number fields. Our approach combines constructions of type II Pad\'{e} approximants with a novel non-vanishing argument for generalized Wronskians of Hermite type. The method applies uniformly across all parameter regimes. Even for p=q+1p = q+1, we extend known results from single-point to multi-point settings over general number fields, in the both complex and pp-adic settings. When p<q+1p < q+1, we establish linear independence results over arbitrary number fields; and for p>q+1p > q+1, we confirm that the values do not satisfy global linear relations in the pp-adic setting. Our results generalize and strengthen earlier work by Chudnovsky's, Nesterenko, Sorokin, Delaygue and others, and demonstrate the flexibility of our Pad\'{e} construction for families of contiguous hypergeometric values.
