Universal Witt vectors in full complete closed p-adic space omega?
Scott Carnahan (8/21/07) comments: "How do we write elements of \Omega_p? The answer quite simple, and is found in Poonenâ€™s undergraduate thesis. The elements are exactly those power series \sum_{r \in \mathbb{Q}} a_r p^r with coefficients given by Teichmüller representatives of \overline{\mathbb{F}}_p, such that the set of exponents with nonzero coefficients forms a well-ordered subset of the rationals."

How is the p-adic norm calculated when using universal witt vectors?
OK. The tag nt.number-theory has been added. |

added a two-letter category (I hope "number theory" is the correct category for p-adic math) |
