Contact structures with singularities
(2018-06-15)
External research report
Open AccessWe 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)
External research report
Open AccessThe 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)
External research report
Open AccessThe 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)
External research report
Open AccessMotivated 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)
External research report
Open AccessWe 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)
External research report
Open AccessIn 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)
External research report
Open AccessA 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 ... -
Metric-locating-dominating partitions in graphs
(2017-11-03)
External research report
Open AccessA partition ¿ = { S 1 ,...,S k } of the vertex set of a connected graph G is a metric-locating partition of G if for every pair of vertices u,v belonging to the same part S i , d ( u,S j ) 6 = d ( v,S j ), for some other ... -
Dominating 2- broadcast in graphs: complexity, bounds and extremal graphs
(2017-10-16)
External research report
Open AccessLimited dominating broadcasts were proposed as a variant of dominating broadcasts, where the broadcast function is upper bounded. As a natural extension of domination, we consider dominating 2-broadcasts along with the ... -
Bifurcation of 2-periodic orbits from non-hyperbolic fixed points
(2017-07-21)
External research report
Open AccessWe introduce the concept of 2-cyclicity for families of one-dimensional maps with a non-hyperbolic fixed point by analogy to the cyclicity for families of planar vector fields with a weak focus. This new concept is useful ...
