An invitation to singular symplectic geometry
(2019)
Article
Accés obertIn this paper we analyze in detail a collection of motivating examples to consider bm-symplectic forms and folded-type symplectic structures. In particular, we provide models in Celestial Mechanics for every bm-symplectic ... -
Coexistence stability in a four-member hypercycle with error tail through center manifold analysis
(2017-09-09)
Article
Accés obertEstablishing the conditions allowing for the stable coexistence in hypercycles has been a subject of intensive research in the past decades. Deterministic, time-continuous models have indicated that, under appropriate ... -
Curves and surfaces with constant nonlocal mean curvature: Meeting Alexandrov and Delaunay
(2018-12-01)
Article
Accés obertWe are concerned with hypersurfaces of RN with constant nonlocal (or fractional) mean curvature. This is the equation associated to critical points of the fractional perimeter under a volume constraint. Our results are ... -
Differential Feedback of MIMO Channel Gram Matrices Based on Geodesic Curves
(2010-12)
Article
Accés restringit per política de l'editorialThis paper proposes a differential quantization strategy to be used in the feedback link of a multiple-input multiple-output (MIMO) communication system. This algorithm is applied to the channel Gram matrix using geodesic ... -
Equivalence between the Hamiltonian and Lagrangian formalisms for constrained systems
(1986-08)
Article
Accés obertThe equivalence between the Lagrangian and Hamiltonian formalism is studied for constraint systems. A procedure to construct the Lagrangian constraints from the Hamiltonian constraints is given. Those Hamiltonian constraints ... -
Equivariant classification of bm-symplectic surfaces
(Springer, 2018-07-24)
Article
Accés obertInspired by Arnold’s classification of local Poisson structures [1] in the plane using the hierarchy of singularities of smooth functions, we consider the problem of global classification of Poisson structures on surfaces. ... -
Geometric Quantization of real polarizations via sheaves
(2013-01)
Report de recerca
Accés obertIn this article we develop tools to compute the Geometric Quantization of a symplectic manifold with respect to a regular Lagrangian foliation via sheaf cohomology. The starting point is the definition of representation ... -
Geometric Quantization of real polarizations via sheaves
(2015)
Article
Accés obertIn this article we develop tools to compute the Geometric Quantization of a symplectic manifold with respect to a regular In this article we develop tools to compute the Geometric Quantization of a symplectic manifold with ... -

Limit cycles bifurcating from a degenerate center
(2016-02-01)
Article
Accés obertWe study the maximum number of limit cycles that can bifurcate from a degenerate center of a cubic homogeneous polynomial differential system. Using the averaging method of second order and perturbing inside the class of ... -
Non-commutative integrable systems on b-symplectic manifolds
(2016)
Report de recerca
Accés obertIn this paper we study non-commutative integrable systems on b-Poisson manifolds. One important source of examples (and motiva- tion) of such systems comes from considering non-commutative systems on manifolds with ... -
Noncommutative integrable systems on b-symplectic manifolds
(Springer, 2016)
Article
Accés obertIn this paper we study noncommutative integrable systems on b-Poisson manifolds. One important source of examples (and motivation) of such systems comes from considering noncommutative systems on manifolds with boundary ... -
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 ... -
Rigidity of Hamiltonian actions on Poisson manifolds
(2011-02-01)
Report de recerca
Accés obertThis paper is about the rigidity of compact group actions in the Poisson context. The main result is that Hamiltonian actions of compact semisimple type are rigid. We prove it via a Nash-Moser normal form theorem for ... -
Stabilisation of state-and-input constrained nonlinear systems via diffeomorphisms: A Sontag's formula approach with an actual application
(2018-09-10)
Article
Accés obertIn this work, we provide a new and constructive outlook for the control of state-and-input constrained nonlinear systems. Previously, explicit solutions have been mainly focused on the finding of a barrier-like Lyapunov ... -
Symplectic and poisson structures with symmetries in interaction
(2014)
Text en actes de congrés
Accés obertHamiltonian actions constitute a central object of study in symplectic geometry. Special attention has been devoted to the toric case. Toric symplectic manifolds provide natural examples of integrable systems and every ...
