A b-symplectic slice theorem
Braddell, Roisin; Miranda Galcerán, Eva; Kiesenhofer, Anna (2022-08-03)
Article
Accés obertIn this article, motivated by the study of symplectic structures on manifolds with boundary and the systematic study of -symplectic manifolds started in Guillemin, Miranda, and Pires Adv. Math. 264 (2014), 864–896, we prove ... -
A b-symplectic slice theorem
Dempsey Bradell, Roisin Mary; Kiesenhofer, Anna; Miranda Galcerán, Eva (2020-09)
Report de recerca
Accés obertIn this article, motivated by the study of symplectic structures on manifolds with bound-ary and the systematic study ofb-symplectic manifolds started in [10], we prove a slice theorem forLie group actions onb-symplectic manifolds -
Action-angle variables and a KAM theorem for b-Poisson manifolds
Kiesenhofer, Anna; Miranda Galcerán, Eva; Scott, Geoffrey (2015-02)
Report de recerca
Accés obertIn this article we prove an action-angle theorem for b-integrable systems on b-Poisson manifolds improving the action-angle theorem contained in [LMV11] for general Poisson manifolds in this setting. As an application, we ... -
Action-angle variables and a KAM theorem for b-Poisson manifolds
Miranda Galcerán, Eva; Kiesenhofer, Anna; Scott, Geoffrey (2016-01-01)
Article
Accés obertIn this article we prove an action-angle theorem for b-integrable systems on b-Poisson manifolds improving the action-angle theorem contained in [14] for general Poisson manifolds in this setting. As an application, we ... -
b-Structures on Lie groups and Poisson reduction
Dempsey Bradell, Roisin Mary; Kiesenhofer, Anna; Miranda Galcerán, Eva (2020-09)
Report de recerca
Accés obertWe introduce the notion of b-Lie group as a pair(G, H) where Gis a Lie group and H is a codimension-one Lie subgroup, and study the associated canonical b-symplectic structure on the b-cotangent bundle bT*G together with ... -
b-Structures on Lie groups and Poisson reduction
Miranda Galcerán, Eva; Kiesenhofer, Anna; Braddell, Roisin (2022-02-11)
Article
Accés obertMotivated by the group of Galilean transformations and the subgroup of Galilean transformations which fix time zero, we introduce the notion of a b-Lie group as a pair where G is a Lie group and H is a codimension-one Lie ... -
Cotangent models for integrable systems on $b$-symplectic manifolds
Miranda Galcerán, Eva; Kiesenhofer, Anna (2016-01)
Report de recerca
Accés obert -
Cotangent models of integrable systems
Miranda Galcerán, Eva; Kiesenhofer, Anna (2016-07)
Article
Accés obertWe associate cotangent models to a neighbourhood of a Liouville torus in symplectic and Poisson manifolds focusing on b-Poisson/b-symplectic manifolds. The semilocal equivalence with such models uses the corresponding ... -
Examples of integrable and non-integrable systems on singular symplectic manifolds
Delshams Valdés, Amadeu; Miranda Galcerán, Eva; Kiesenhofer, Anna (2016-12)
Report de recerca
Accés obertWe present a collection of examples borrowed from celes- tial mechanics and projective dynamics. In these examples symplectic structures with singularities arise naturally from regularization trans- formations, Appell's ... -
Integrable systems on b-symplectic manifolds
Kiesenhofer, Anna (Universitat Politècnica de Catalunya, 2016-12-21)
Tesi
Accés obertThe study of b-symplectic manifolds was initiated in 2012 by the works of Victor Guillemin, Eva Miranda and Ana Rita Pires (Adv. Math. 264 (2014), 864¿896). These manifolds, which can be understood as symplectic manifolds ... -
Non-commutative integrable systems on b-symplectic manifolds
Miranda Galcerán, Eva; Kiesenhofer, Anna (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 ...
