Open problems, questions, and challenges in finite-dimensional integrable systems
(Royal Society, 2018-05-14)
Article
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 ... -
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. ... -
Zeroth poisson homology, foliated cohomology and perfect poisson manifolds
(Springer, 2018)
Article
Accés obertWe prove that for regular Poisson manifolds, the zeroth homology group is isomorphic to the top foliated cohomology group and we give some applications. In particular, we show that for regular unimodular Poisson manifolds ... -

On geometric quantization of b-symplectic manifolds
(2018-05-20)
Article
Accés obertWe study a notion of pre-quantization for b-symplectic manifolds. We use it to construct a formal geometric quantization of b-symplectic manifolds equipped with Hamiltonian torus actions with nonzero modular weight. We ... -
Integrable systems and closed one forms
(2018-05-15)
Article
Accés obertIn the first part of this paper we revisit a classical topological theorem by Tischler (1970) and deduce a topological result about compact manifolds admitting a set of independent closed forms proving that the manifold ... -
An invitation to singular symplectic geometry
(2017)
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 ... -
Classification of b^m-Nambu structures of top degree
(2018-01)
Article
Accés obertWe obtain sufficient conditions for the existence and uniqueness of a positive compact almost automorphic solution to a logistic equation with discrete and continuous delay. Moreover, we provide a counterexample to some ... -
Constancy regions of mixed multiplier ideals in two-dimensional local rings with rational singularities
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2018)
Article
Accés obertThe aim of this paper is to study mixed multiplier ideals associated with a tuple of ideals in a two-dimensional local ring with a rational singularity. We are interested in the partition of the real positive orthant given ... -
New algebraic conditions for the identification of the relative position of two coplanar ellipses
(2017-05-01)
Article
Accés restringit per política de l'editorialThe identification of the relative position of two real coplanar ellipses can be reduced to the identification of the nature of the singular conics in the pencil they define and, in general, their location with respect to ... -
Effective computation of base points of ideals in two-dimensional local rings
(2018-01-04)
Article
Accés restringit per política de l'editorial© 2018 Elsevier Ltd. We provide an algorithm that allows to describe the minimal log-resolution of an ideal in a smooth complex surface from the minimal log-resolution of its generators. In order to make this algorithm ... -
Homotopy linear algebra
(2018-04)
Article
Accés obertBy homotopy linear algebra we mean the study of linear functors between slices of the 8-category of 8-groupoids, subject to certain finiteness conditions. After some standard definitions and results, we assemble said slices ...
