Linear independence of values of hypergeometric functions and arithmetic Gevrey series
Abstract
We prove new linear independence results for the values of generalized hypergeometric functions 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 , we extend known results from single-point to multi-point settings over general number fields, in the both complex and -adic settings. When , we establish linear independence results over arbitrary number fields; and for , we confirm that the values do not satisfy global linear relations in the -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.
