Abstract:
We prove here that at least one of the two 2-adic numbers which are the values at z=1 of the sums in Q2 of the series f0(λ)=∞∑n=0(λ)nλn,f1(λ)=∞∑n=0(λ+1)nλn, where λ is a certain polyadic Liouville number. The series considered converge in any field Qp .We deal here with Q2. The symbol (γ)n denotes Pochhammer symbol, i.e. (γ)0=1 , and for n≥1 we have(γ)n=γ(γ+1)...(γ+n−1). The values of these series were also calculated at polyadic Liouville number. The canonic expansion of a polyadic number λ is of the form λ=∞∑n=0ann!,an∈Z,0≤an≤n. This series converges in any field of p− adic numbers Qp . We call a polyadic number λ a polyadic Liouville number, if for any n and P there exists a positive integer A such that for all primes p ,satisfying p≤P the inequality |λ−A|p<|A|−n holds. It was proved earlier that the Liouville polyadic number is transcendental in any field Qp. In other words,the Liouville polyadic number is globally transcendental. It allowed to prove using some equality that there exists an infinite set of p−adic fields Qp where at least one of the numbers f0(z),f1(z). Here we prove the transcendence of values in the field Q2.
