# On Dwork’s \(p\)-Adic Formal Congruences Theorem and Hypergeometric Mirror Maps

Share this page
*E. Delaygue; T. Rivoal; J. Roques*

Using Dwork's theory, the authors prove a broad
generalization of his famous \(p\)-adic formal congruences
theorem. This enables them to prove certain \(p\)-adic
congruences for the generalized hypergeometric series with rational
parameters; in particular, they hold for any prime number
\(p\) and not only for almost all primes. Furthermore, using
Christol's functions, the authors provide an explicit formula for the
“Eisenstein constant” of any hypergeometric series with
rational parameters.

As an application of these results, the authors obtain an
arithmetic statement “on average” of a new type concerning
the integrality of Taylor coefficients of the associated mirror
maps. It contains all the similar univariate integrality results in
the literature, with the exception of certain refinements that hold
only in very particular cases.
