Given a prime number p and the Galois orbit O(x) of a normal element x of ℂp, the topological completion of the algebraic closure of the field of p-adic numbers, we study the Iwasawa algebra of O(x)…

Abstract Let p be a prime number, Q p the field of p -adic numbers, Q p a fixed algebraic closure of Q p , and C p the completion of Q p . For elements T ∈ C p which satisfy a certain diophantine…
On the Closed Subfields ofCp

- Mathematics
- 1 February 1998
The so called ``p-adic analog of the field of complex numbers'' Cp (see [6, 7, 21]) seems to be a very interesting object to study, both from an algebraic and an analytic point of view. Particularly…
The Generating Degree of ℂ p

- 1 March 2001
Abstract The generating degree $\text{g}\deg \left( A \right)$ of a topological commutative ring $A$ with char $A\,=\,0$ is the cardinality of the smallest subset $M$ of $A$ for which the subring…

The notion of trace for an element in an algebraic extension of a field can be extended for (not necessary algebraic) elements of same extensions of a complete valued field (see [2]). However there…
