Modular classes of Jacobi bundles

Diallo, Mamadou Lamarana; Wade, Aïssa

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-021-00227-2

This paper is the first part of a dilogy devoted to modular classes of Jacobi structures from the general line bundle perspective as well as their associated Lie algebroids. First, we explain the relationship between Jacobi algebroids and their associated Gerstenhaber-Jacobi algebras. Then, we...

The classifying Lie algebroid of a geometric structure II: G-structures with connection

Fernandes, Rui Loja; Struchiner, Ivan

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-021-00272-x

Given a G-structure with connection satisfying a regularity assumption we associate to it a classifying Lie algebroid. This algebroid contains all the information about the equivalence problem and is an example of a G-structure Lie algebroid. We discuss the properties of this algebroid, the...

Liouvillian solutions for second order linear differential equations with polynomial coefficients

Acosta-Humánez, Primitivo B.; Blázquez-Sanz, David; Venegas-Gómez, Henock

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-020-00186-0

In this paper we present an algebraic study concerning the general second order linear differential equation with polynomial coefficients. By means of Kovacic’s algorithm and asymptotic iteration method we find a degree independent algebraic description of the spectral set: the subset, in the...

The higher Riemann-Hilbert correspondence and principal 2-bundles

Abad, Camilo Arias; Vásquez, Sebastián Vélez

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-021-00239-y

In this note we show that the holonomies for higher local systems provided by the higher Riemann-Hilbert correspondence coincide with those associated to principal 2-bundles where both formalisms meet.

20 Open questions about deformations of compactifiable manifolds

Ballico, Edoardo; Gasparim, Elizabeth; Rubilar, Francisco

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-021-00213-8

Deformation theory of complex manifolds is a classical subject with recent new advances in the noncompact case using both algebraic and analytic methods. In this note we recall some concepts of the existing theory and introduce new notions of deformations for manifolds with boundary, for...

On the Hodge conjecture for quasi-smooth intersections in toric varieties

Bruzzo, Ugo; Montoya, William

2021 São Paulo Journal of Mathematical Sciences

doi:10.1007/s40863-021-00247-y

We establish the Hodge conjecture for some subvarieties of a class of toric varieties. First we study quasi-smooth intersections in a projective simplicial toric variety, which is a suitable notion to generalize smooth complete intersection subvarieties in the toric environment, and in particular...
