Extending a valuation centered in a local domain to the formal completion
(London Mathematical Society, 2012-09)
Let (R; m; k) be a local noetherian domain with field of fractions K and R_v a valuation ring, dominating R (not necessarily birationally). Let v|K be the restriction of v to K; by definition, v|K is centered at R. Let ...

Valuations in fields of power series
(European Mathematical Society, 2003)
This paper deals with valuations of fields of formal meromorphic functions and their residue fields. We explicitly describe the residue fields of the monomial valuations. We also classify all the discrete rank one valuations ...

MacMahon symmetric functions, the partition lattice, and young subgroups
(Elsevier, 2001-11)
A MacMahon symmetric function is a formal power series in a finite number of alphabets that is invariant under the diagonal action of the symmetric group. In this article, we show that the MacMahon symmetric functions are ...

Finite monodromy of some families of exponential sums
(Elsevier, 2019-04)
Given a prime p and an integer d > 1, we give a numerical criterion to decide whether the ℓ-adic sheaf associated to the one-parameter exponential sums t 7→P x ψ(xd + tx) over Fp has finite monodromy or not, and work ...

Rank one discrete valuations of power series fields
(Taylor & Francis, 2007)
In this paper we study rank one discrete valuations of the field k((X1, . . . , Xn)) whose center in k[[X1, . . . , Xn]] is the maximal ideal. In sections 2 to 6 we give a construction of a system of parametric equations ...

On the generalised phase kick-back and its applications
(2024-04-04)
La computación cuántica es una rama que ha adquirido creciente relevancia en los últimos tiempos, sobre todo tras el descubrimiento por parte de Peter Shor en los años 90 de un algoritmo para factorizar enteros de forma ...

Galois representations and Galois groups over Q
(Springer, 2015)
In this paper we generalize results of P. Le Duff to genus n hyperelliptic curves. More precisely, let C/Q be a hyperelliptic genus n curve, let J(C) be the associated Jacobian variety and let ¯ρℓ : GQ → GSp(J(C)[ℓ]) be ...

Computer algebra and algebraic analysis
(Universidad de La Rioja, 2010)
Este artículo describe algunas aplicaciones del Álgebra Computacional al Análisis Algebraico, también conocido como teoría de D-módulos, es decir, el estudio algebraico de sistemas lineales de ecuaciones en derivadas ...

Parabolic subgroups of large-type Artin groups
(Cambridge University Press, 2022-09-12)
We show that the geometric realisation of the poset of proper parabolic subgroups of a large-type Artin group has a systolic geometry. We use this geometry to show that the set of parabolic subgroups of a large-type Artin ...
