Divisors of expected Jacobian type
(2021)
Article
Open AccessDivisors whose Jacobian ideal is of linear type have received a lot of attention recently because of its connections with the theory of D-modules. In this work we are interested on divisors of expected Jacobian type, that ... -
Current distributions in wide YBCO tapes
(Elsevier, 2012)
Article
Open AccessThe need of a better mechanical behaviour and the stabilization of coated conductors for applications, as Magnets, cables or Fault Current Limiters, has motivated the lamination of tapes with stainless steel or copper ... -
Current distribution in HTSC tapes obtained by inverse problem calculation
(Institute of Physics (IOP), 2010)
Article
Open AccessThe development of SC devices based on HTSC tapes requires a deep knowledge of the current distribution in both pre-saturation and post-saturation regimes. Magnetic measurements have shown the possibilities ... -
Computation of critical current in artificially structurated bulk samples from Hall measurements
(Institute of Physics (IOP), 2008)
Article
Open AccessHigh-temperature superconducting artificially structured bulk samples, such as bulks with slanted drills or welds of different pieces along the c-axis with holes drilled in different asymmetric positions, ... -
La biblioteca matemàtica digital
(Societat Catalana de Matemàtiques (SCM), 2003-07)
Article
Open AccessLa biblioteca matemàtica digital és un somni, que ha esdevingut un projecte gràcies als avenços de la tecnologia informàtica dels darrers anys. -
Gabriel–Zisman cohomology and spectral sequences
(Springer Nature, 2021-02-10)
Article
Restricted access - publisher's policyExtending constructions by Gabriel and Zisman, we develop a functorial framework for the cohomology and homology of simplicial sets with very general coefficient systems given by functors on simplex categories into abelian ... -
Symplectic Lefschetz fibrations of curves as gonal coverings
(2013-08)
Article
Open AccessWe show that after a finite base change every symplectic Lefschetz fibration f : X ¿ B of genus g > 3 curves over a closed oriented surface becomes a finite covering of degree g 2 + 1 or g 2 + 32 of a family of spheres ... -
Of limit key polynomials
(2021-04-01)
Article
Open AccessLet ν be a valuation of arbitrary rank on the polynomial ring K[x] with coefficients in a field K. We prove comparison theorems between MacLane-Vaquié key polynomials for valuations μ ≤ν and abstract key polynomials for ... -
The singular Weinstein conjecture
(2021-07-23)
Article
Open AccessIn this article, we investigate Reeb dynamics on bm-contact manifolds, previously introduced in [37], which are contact away from a hypersurface Zbut satisfy certain transversality conditions on Z. The study of these contact ... -
On the singular Weinstein conjecture and the existence of escape orbits for b-Beltrami fields
(2021-07-01)
Article
Open AccessMotivated by Poincaré’s orbits going to infinity in the (restricted) three-body problem (see [26] and [6]), we investigate the generic existence of heteroclinic-like orbits in a neighbourhood of the critical set of a ... -
Geometric quantization via cotangent models
(2021-09)
Article
Open AccessIn this article we give a universal model for geometric quantization associated to a real polarization given by an integrable system with non-degenerate singularities. This universal model goes one step further than the ... -
Discrepancies between observational data and theoretical forecast in single field slow roll inflation
(2016-09-09)
Article
Open AccessThe PLANCK collaboration has determined, or greatly constrained, values for the spectral parameters of the CMB radiation, namely the spectral index ns, its running as, the running of the running ßs, using a growing body ...
