Semiclassical quantification of some two degree of freedom potentials: A differential Galois approach
(2024-01-01)
Article
Accés obertIn this work we explain the relevance of the Differential Galois Theory in the semiclassical (or WKB) quantification of some two degree of freedom potentials. The key point is that the semiclassical path integral quantification ... -

Marked graphs and the chromatic symmetric function
(2023-09-30)
Article
Accés obertThe main result of this paper is the introduction of marked graphs and the marked graph polynomials ( -polynomial) associated with them. These polynomials can be defined via a deletion-contraction operation. These polynomials ... -
On the metric representation of the vertices of a graph
(2023-09-12)
Article
Accés restringit per política de l'editorialThe metric representation of a vertex u in a connected graph G respect to an ordered vertex subset is the vector of distances . A vertex subset W is a resolving set of G if , for every with . Thus, a resolving set with n ... -
Identifiability in robust estimation of tree structured models
(2024-02-01)
Article
Accés restringit per política de l'editorialConsider the problem of learning undirected graphical models on trees from corrupted data. Recently Katiyar, Shah, and Caramanis showed that it is possible to recover trees from noisy binary data up to a small equivalence ... -
New slope inequalities for families of complete intersections
(2024-01-01)
Article
Accés obertWe prove f-positivity of Ox (1) for arbitrary dimensional fibrations over curves f:X¿B whose general fibre is a complete intersection. In the special case where the family is a global complete intersection, we prove numerical ... -
El problema inverso de autovalores para matrices de Jacobi no negativas y bisimétricas
(Universidad de Cádiz, 2023)
Text en actes de congrés
Accés obertEn esta comunicación presentamos nuestros recientes resultados en el problema inverso nonegativo para matrices de Jacobi bisimétricas, que consisten en nuevas condiciones necesarias para que una lista dada de números ... -
Bipartite secret sharing and staircases
(Elsevier, 2024-05-01)
Article
Accés obertBipartite secret sharing schemes have a bipartite access structure in which the set of participants is divided into two parts and all participants in the same part play an equivalent role. Such a bipartite scheme can be ... -
Speeding up random walk mixing by starting from a uniform vertex
(Project Euclid, 2024-01-01)
Article
Accés obertThe theory of rapid mixing random walks plays a fundamental role in the study of modern randomised algorithms. Usually, the mixing time is measured with respect to the worst initial position. It is well known that the ... -
Existence and symmetry of periodic nonlocal-CMC surfaces via variational methods
(De Gruyter, 2023-10-05)
Article
Accés restringit per política de l'editorialThis paper provides the first variational proof of the existence of periodic nonlocal-CMC surfaces. These are nonlocal analogues of the classical Delaunay cylinders. More precisely, we show the existence of a set in Rn ... -
A Weierstrass extremal field theory for the fractional Laplacian
(De Gruyter, 2023-10-27)
Article
Accés restringit per política de l'editorialIn this paper, we extend, for the first time, part of the Weierstrass extremal field theory in the Calculus of Variations to a nonlocal framework. Our model case is the energy functional for the fractional Laplacian (the ... -
Graphs attaining the upper bound on the isolation number
(Universidad de Cádiz, 2023)
Text en actes de congrés
Accés obertA set D of vertices of a graph is isolating if the set of vertices not belonging to D or not having a neighbour in D is independent. The isolation number of a graph G, denoted by ¿(G), is the minimum cardinality of an ...
