The main sources for the Arte Mayor in sixteenth century Spain
(2018-01-18)
Article
Restricted access - publisher's policyOne of the main changes in European Renaissance mathematics was the progressive development of algebra from practical arithmetic, in which equations and operations began to be written with abbreviations and symbols rather ... -
Weak-type boundedness of the Fourier transform on rearrangement invariant function spacest
(2018-06-08)
Article
Open AccessWe study several questions about the weak-type boundedness of the Fourier transform F on rearrangement invariant spaces. In particular, we characterize the action of F as a bounded operator from the minimal Lorentz space ... -
Hysteretic active control of base-isolated buildings
(2018-06-01)
Article
Open AccessIn this work, an active control law for base-isolated buildings is proposed. The crucial idea comes from the observation that passive base-isolation systems are hysteretic. Thus, an hysteretic active control strategy is ... -
The spectral excess theorem for graphs with few eigenvalues whose distance-2 or distance-1-or-2 graph is strongly regular
(Taylor & Francis, 2018-07)
Article
Open AccessWe study regular graphs whose distance-2 graph or distance-1-or-2 graph is strongly regular. We provide a characterization of such graphs G (among regular graphs with few distinct eigenvalues) in terms of the spectrum ... -
An improved upper bound for the order of mixed graphs
(2018-07)
Article
Open AccessA mixed graph G can contain both (undirected) edges and arcs (directed edges). Here we derive an improved Moore-like bound for the maximum number of vertices of a mixed graph with diameter at least three. Moreover, a ... -
Zeroth poisson homology, foliated cohomology and perfect poisson manifolds
(Springer, 2018)
Article
Open AccessWe prove that for regular Poisson manifolds, the zeroth homology group is isomorphic to the top foliated cohomology group and we give some applications. In particular, we show that for regular unimodular Poisson manifolds ... -

Viable inflationary evolution from Einstein frame loop quantum cosmology
(American Physical Society (APS), 2018-04-27)
Article
Open AccessIn this work we construct a bottom-up reconstruction technique for loop quantum cosmology scalar-tensor theories, from the observational indices. Particularly, the reconstruction technique is based on fixing the functional ... -
Bulk viscous quintessential inflation
(2018-04-01)
Article
Restricted access - publisher's policyIn a spatially-flat Friedmann–Lemaître–Robertson–Walker universe, the incorporation of bulk viscous process in general relativity leads to an appearance of a nonsingular background of the universe that both at early and ... -
Teaching engineers in the seventeenth century: european influences in Portugal
(2018-06-09)
Article
Restricted access - publisher's policyThe practice of mathematics underwent a major transformation in the seventeenth century due to new procedures and concepts that also showed their utility for military architecture. The circulation of this knowledge can be ... -
Antisymmetry of solutions for some weighted elliptic problems
(2018-03-17)
Article
Restricted access - publisher's policyThis article concerns the antisymmetry, uniqueness, and monotonicity properties of solutions to some elliptic functionals involving weights and a double well potential. In the one-dimensional case, we introduce the continuous ... -
Las habilidades sociales del docente universitario: una formación hacia la competencia interpersonal
(2014-07-14)
Article
Open AccessDesde el ICE de la UPC se ha planteado una nueva formación dirigida a todo el profesorado basada en la adquisición de competencias docentes. Uno de los módulos de formación puesto en marcha trabaja la adquisición de la ...
