On the Brauer p-dimension of Henselian discrete valued fields of residual characteristic p > 0

نویسندگان

چکیده

Let $(K, v)$ be a Henselian discrete valued field with residue $\widehat K$ of characteristic $p$, and Brd$_{p}(K)$ the Brauer $p$-dimension $K$. This paper shows that Brd$_{p}(K) \ge n$, if $[\widehat K\colon \widehat K ^{p}] = p ^{n}$, for some $n \in \mathbb{N}$. It proves \infty $ only $.

HENSELIAN RESIDUALLY p-ADICALLY CLOSED FIELDS

In (Arch. Math. 57 (1991), pp. 446–455), R. Farré proved a positivstellensatz for real-series closed fields. Here we consider p-valued fields 〈K, vp〉 with a non-trivial valuation v which satisfies a compatibility condition between vp and v. We use this notion to establish the p-adic analogue of real-series closed fields; these fields are called henselian residually p-adically closed fields. Fir...

Singularities in characteristic 0 and characteristic p

1 Characteristic 0 We start with a basic question: given a polynomial f ∈ C[z1, · · · , zn] with a singularity at 0, how can we measure the “singularness” of this polynomial in a precise way? In other words: we can look at various singularities and see intuitively that some singularities are worse than others. For instance, it feels like a transverse self-intersection is probably not as bad as ...

BRAUER-TYPE RESULTS ON SEMIGROUPS OVER p-ADIC FIELDS

In this paper we consider the following problem. Let k < K be fields. Suppose S ⊂ Mn(K) is an absolutely irreducible multiplicative semigroup with the property that the spectrum of every a ∈ S is contained in k. Does it follow that S is simultaneously realizable in Mn(k), that is, does there exist a p ∈ GLn(K) such that pSp−1 ⊂ Mn(k)? The overfield K plays no essential role in this situation. C...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
