چکیده
We use the Dwork–Frobenius operator to prove an integrality result for \mbox {$A$-hypergeometric} series whose coefficients are factorial ratios. As a special case, we generalize one direction of classical Landau on factoria

Integrality of hook ratios
We study integral ratios of hook products of quotient partitions. This question is motivated by an analogous question in number theory concerning integral factorial ratios. We prove an analogue of a theorem of Landau that already applied in the factorial case. Under the additional condition that the ratio has one more factor on the denominator than the numerator, we provide a complete classific...
متن کاملOn the Integrality of the Taylor Coefficients of Mirror Maps
Abstract. We show that the Taylor coefficients of the series q(z) = z exp(G(z)/F(z)) are integers, where F(z) and G(z) + log(z)F(z) are specific solutions of certain hypergeometric differential equations with maximal unipotent monodromy at z = 0. We also address the question of finding the largest integer u such that the Taylor coefficients of (zq(z)) are still integers. As consequences, we are...
متن کاملRelations among Dirichlet Series Whose Coefficients Are Class Numbers of Binary Cubic Forms Ii
As a continuation of the authors’ and Wakatsuki’s previous paper [5], we study relations among Dirichlet series whose coefficients are class numbers of binary cubic forms. We show that, for all integral models of the space of binary cubic forms, the associated Dirichlet series satisfy self dual identities.
متن کاملOn the Coefficients in Asymptotic Factorial Expansions
Here p and q are non-negative integers with pûq\ the a i and p¡ denote arbitrary complex parameters and w denotes a complex variable. It is known from a lemma which appears in the work of W. B. Ford [l ], E. M. Wright [5], and H. K. Hughes [2] that Pgq(w) admits an asymptotic factorial expansion in every right half-plane. Moreover, it follows from their investigations that the coefficients occu...
متن کاملOn the irrationality of factorial series II
In this paper we give irrationality results for numbers of the form ∑∞ n=1 an n! where the numbers an behave like a geometric progression for a while. The method is elementary, not using differentiation or integration. In particular, we derive elementary proofs of the irrationality of π and em for Gaussian integers m 6= 0.
