The formal series Witt transform
نویسنده
چکیده
Given a formal power series f(z) ∈ C[[z]] we define, for any positive integer r, its rth Witt transform, W (r) f , by W (r) f (z) = 1 r ∑ d|r μ(d)f(z d)r/d, where μ denotes the Möbius function. The Witt transform generalizes the necklace polynomials, M(α;n), that occur in the cyclotomic identity 1 1− αy = ∞

Conjugacy classes of series in positive characteristic and Witt vectors
Let k be the algebraic closure of Fp and K be the local field of formal power series with coefficients in k. The aim of this paper is the description of the set Yn of conjugacy classes of series of order p for the composition law. This work is concerned with the formal power series with coefficients in a field of characteristic p which are invertible and of finite order p for the composition la...
متن کاملWitt Vectors and a Question of Keating and Rudnick
Following Keating and Rudnick, we say that a character Λ : B× → C× is “even” if it is trivial on the subgroup k×. The quotient group B×/k× is the group of “big” Witt vectors mod X with values in k. Recall that for any ringA, the groupBigWitt(A) is simply the abelian group 1 +XA[[X]] of formal series with constant term 1, under multiplication of formal series. In this group, the elements 1 +XA[[...

Let $K$ be a field of characteristic$p>0$, $K[[x]]$, the ring of formal power series over $ K$,$K((x))$, the quotient field of $ K[[x]]$, and $ K(x)$ the fieldof rational functions over $K$. We shall give somecharacterizations of an algebraic function $fin K((x))$ over $K$.Let $L$ be a field of characteristic zero. The power series $finL[[x]]$ is called differentially algebraic, if it satisfies...
متن کاملOn the Artin-hasse Exponential Series
1. Professor G. Whaples has kindly drawn my attention to the very similar properties enjoyed by the series which I called the Witt hyperexponential in a recent paper [2], and a series which he had previously defined, using the Artin-Hasse exponential series [5]; the main fact is that both series define a homomorphism of the Witt group W onto the multiplicative group W*. In answer to his questio...
متن کاملWitt rings of quadratically presentable fields
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability. It turns out that the classical notion of the Witt ring of symmetric bilinear forms over a field makes sense in the context of {tmem{quadratically p...
