Periodic orbits of discrete and continuous dynamical systems via Poincaré-Miranda theorem
(2018-09-17)
Report de recerca
Accés obertWe present a systematic methodology to determine and locate analytically isolated periodic points of discrete and continuous dynamical systems with algebraic nature. We apply this method to a wide range of examples, including ... -
Group inverse of the laplacian of connections of networks
(2018-03-25)
Report de recerca
Accés restringit per política de l'editorialIn previous works the group inverse of a network obtained by some perturbations, as the deletion of a vertex, the addition of a new vertex, contraction of an edge, etc. is obtained in terms of the group inverse of the ... -
Neighbor-locating colorings in graphs
(2018-06-29)
Report de recerca
Accés obertA k -coloring of a graph G is a k -partition ¿ = { S 1 ,...,S k } of V ( G ) into independent sets, called colors . A k -coloring is called neighbor-locating if for every pair of vertices u,v belonging to the same color S ... -
Contact structures with singularities
(2018-06-15)
Report de recerca
Accés obertWe study singular contact structures, which are tangent to a given smooth hypersurface Z and satisfy certain transversality conditions. These singular contact structures are determined by the kernel of non-smooth differential ... -

A route to chaos in the Boros-Moll map
(2018-04-18)
Report de recerca
Accés obertThe Boros-Moll map appears as a subsystem of a Landen transformation associated to certain rational integrals and its dynamics is related to the convergence of them. In the paper, we study the dynamics of a one-parameter ... -
Open problems, questions, and challenges in finite-dimensional integrable systems
(2018-04-11)
Report de recerca
Accés obertThe paper surveys open problems and questions related to different aspects of integrable systems with finitely many degrees of freedom. Many of the open problems were suggested by the participants of the conference ... -

The geometry of E-manifolds
(2018-02-09)
Report de recerca
Accés obertMotivated by the study of symplectic Lie algebroids, we study a describe a type of algebroid (called an E-tangent bundle) which is particularly well-suited to study of singular differential forms and their cohomology. ... -
Periodic points of a Landen transformation
(2018-01-12)
Report de recerca
Accés obertWe prove the existence of 3-periodic orbits in a dynamical system associated to a Landen transformation previously studied by Boros, Chamberland and Moll, disproving a conjecture on the dynamics of this planar map introduced ... -
Some manifolds of periodic orbits in the restricted three body problem
(1984)
Report de recerca
Accés obertIn the present paper we give some numerical results about natural families of periodic orbits, which emanate from limiting orbits around equilateral equilibrium points of the Restricted Three Body Problem, when the mass ... -
Locating domination in bipartite graphs and their complements
(2017-11-03)
Report de recerca
Accés obertA set S of vertices of a graph G is distinguishing if the sets of neighbors in S for every pair of vertices not in S are distinct. A locating-dominating set of G is a dominating distinguishing set. The location-domination ...
