Abstract:
The article takes a look at transcendence and algebraic independence problems, introduces statements and proofs of theorems for some kinds of elements from direct product of p-adic fields and polynomial estimation theorem. Let Qp be the p-adic completion of Q, Ωp be the completion of the algebraic closure of Qp, g=p1p2…pn be a composition of separate prime numbers, Qg be the g-adic completion of Q, in other words Qp1⊕…⊕Qpn. The ring Ωg≅Ωp1⊕…⊕Ωpn, a subring Qg, transcendence and algebraic independence over Qg are under consideration. Here are appropriate theorems for numbers not only like α=∞∑j=0ajgrj where aj∈Zg, and non-negative rationals rj increase strictly unbounded. But, for numbers f(α), where f(z)=∞∑j=0cjzj∈Zg[[z]]. Furthermore, let ˆQ≅∏pQp be the ring of polyadic numbers, then, the article takes a look at ˆΩ=∏pΩp, there are similar results for numbers like f(α), where f(z)=∞∑j=0cjzj∈ˆZ[[z]], α=∞∑k=1akgrk, ak∈Zg, g=(p1,…,pn,…).
Keywords:
p-adic numbers, g-adic numbers, polyadic numbers, transcendence, algebraic independence.
