Abstract:
We study here polyadic Liouville numbers, which are involved in a series of recent papers. The author considered the series
$$ f_{0}(\lambda)=\sum_{n=0}^\infty (\lambda)_{n}\lambda^{n}, f_{1}(\lambda)=\sum_{n=0}^\infty (\lambda +1)_{n}\lambda^{n},$$
where
$ \lambda $ is a certain polyadic Liouville number. The series considered converge in any field
$ \mathbb{\mathrm{Q}}_p $. Here
$(\gamma)_{n}$ denotes Pochhammer symbol, i.e.
$(\gamma)_{0}=1$, and for
$n\geq 1$ we have
$ (\gamma)_{n}=\gamma(\gamma+1)\dots(\gamma+n-1)$. The values of these series were also calculated at polyadic Liouville number. The canonic expansion of a polyadic number
$\lambda$ is of the form
$$ \lambda= \sum_{n=0}^\infty a_{n} n!, a_{n}\in\mathbb{\mathrm{Z}}, 0\leq a_{n}\leq n.$$
This series converges in any field of
$p$-adic numbers
$ \mathbb{\mathrm{Q}}_p $. We call a polyadic number
$\lambda$ a polyadic Liouville number, if for any
$n$ and
$P$ there exists a positive integer
$A$ such that for all primes
$p$, satisfying
$p\leq P$ the inequality
$$\left|\lambda -A \right|_{p}<A^{-n}$$
holds. The paper gives a simple proof that the Liouville polyadic number is transcendental in any field
$\mathbb{\mathrm{Q}}_p.$ In other words,the Liouville polyadic number is globally transcendental. We prove here a theorem on approximations of a set of
$p$-adic numbers and it's corollary — a sufficient condition of the algebraic independence of a set of
$p$-adic numbers. We also present a theorem on global algebraic independence of polyadic numbers.
