On a conjecture by Kauffman on alternative and pseudoalternating links
(Elsevier, 2015-06)It is known that alternative links are pseudoalternating. In 1983 Louis Kauffman conjectured that both classes are identical. ...

On a determinantal formula of Tadić
(Johns Hopkins University Press, 2014-02)We study a special class of irreducible representations of GLn over a local non-Archimedean field which we call ladder ...

On conjectures of Sato-Tate and Bruinier-Kohnen
(Springer, 2015-04)This article covers three topics. (1) It establishes links between the density of certain subsets of the set of primes and ...

On determinant functors and K-theory
(Universitat Autònoma de Barcelona, 2015)We extend Deligne’s notion of determinant functor to Waldhausen categories and (strongly) triangulated categories. We ...

On dilatation factors of braids on three strands
(World Scientific Publishing, 2015-04)In this work we present a natural surjective map from rigid braids in B3 (in Garside sense) to SL2(N). This map provides ...

On irregular binomial D-modules
(Springer, 2012-12)We prove that a holonomic binomial D–module MA(I, β) is regular if and only if certain associated primes of I determined ...

On loxodromic actions of Artin–Tits groups
(Elsevier, 2018-04-10)Artin–Tits groups act on a certain delta-hyperbolic complex, called the “additional length complex”. For an element of the ...

On reduction curves and Garside properties of braids
(American Mathematical Society, 2011)In this paper we study the reduction curves of a braid, and how they can be used to decompose the braid into simpler ones ...

On simultaneous arithmetic progressions on elliptic curves
(Taylor & Francis, 2006)In this paper we study elliptic curves which have a number of points whose coordinates are in arithmetic progression. We ...

On the bracket of integrable derivations
(Elsevier, 2021-05-15)We prove that any multi-variate Hasse–Schmidt derivation can be decomposed in terms of substitution maps and uni-variate ...

Artículo
On the centralizer of generic braids
(De Gruyter, 2018-11)We study the centralizer of a braid from the point of view of Garside theory, showing that generically a minimal set of ...

On the computation of the Apéry set of numerical monoids and affine semigroups
(Springer, 2014-10-01)A simple way of computing the Apéry set of a numerical semigroup (or monoid) with respect to a generator, using Groebner ...

On the cycling operation in braid groups
(Elsevier, 2008-09-06)The cycling operation is a special kind of conjugation that can be applied to elements in Artin’s braid groups, in order ...

On the dimension of discrete valuations of k ((X1, ..., Xn))
(Elsevier, 2001-07-01)Let v be a rank-one discrete valuation of the field Kn=k((X1,…,Xn)). We know, after [1], that if n=2 then the dimension ...

On the functoriality of cohomology of categories
(Elsevier, 2006-03)In this paper we show that the Baues-Wirsching complex used to define cohomology of categories is a 2-functor from a certain ...

Artículo
On the local monodromy of AA-hypergeometric functions and some monodromy invariant subspaces
(EMS Press, 2019-04-09)We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted ...

Artículo
On the logarithmic comparison theorem for integrable logarithmic connections
(London Mathematical Society, 2009)Let X be a complex analytic manifold, D ⊂ X a free divisor with jacobian ideal of linear type (e.g. a locally quasi-homogeneous ...

On the minimal positive standardizer of a parabolic subgroup of an Artin–Tits group
(Springer, 2018-09-22)The minimal standardizer of a curve system on a punctured disk is the minimal positive braid that transforms it into a ...

Artículo
On the modules of m-integrable derivations in non-zero characteristic
(Elsevier, 2012-03-20)Let k be a commutative ring and A a commutative k-algebra. Given a positive integer m, or m = ∞, we say that a k-linear ...

On the number of rational points on curves over finite fields with many automorphisms
(Elsevier, 2013-01)Using Weil descent, we give bounds for the number of rational points on two families of curves over finite fields with a ...
