Lie semigroups, homotopy, and global extensions of local homomorphisms
(Heldermann VerlagLemgo, 2015)
For a finite dimensional connected Lie group G with Lie algebra g, we consider a Lie-generating Lie wedge W [...] g. If S is a Lie subsemigroup of G with subtangent wedge W we give sufficient conditions for S to be free ...

Schubert Derivations on the Infinite Wedge Power
(2020-01-01)
The Schubert derivation is a distinguished Hasse–Schmidt derivation on the exterior algebra of a free abelian group, encoding the formalism of Schubert calculus for all Grassmannians at once. The purpose of this paper is ...

Bacia pré-siluriana na porção centro-oeste da Província Parnaíba, NE do Brasil
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2017-08-31)
Pre-Silurian grabens have been interpreted in the substrate of Parnaíba Basin, with implications in the subsidence control and consequent evolution of the syneclise at the Phanerozoic. This research presents the results ...
DiffAlg: a Differential Algebra Package
(Mathematical Science Publ, 2019-03-04)
In this article we present DiffAlg.m2, a differential algebra package for Macaulay2. It can perform the following operations: wedge products and exterior differentials of differential forms, contraction and Lie derivatives ...
The boson-fermion correspondence from linear ODEs
(Elsevier B.V., 2014-10-01)
There is a bridge between generic linear Ordinary Differential Equations (ODEs), Schubert Calculus and the bosonic-fermionic representations of the Heisenberg algebra. For a finite-order generic linear ODE, the role of the ...
Study on 24 hours IOP study and glaucoma frequency in patients with obstructive sleep apnea syndromeEstudo do comportamento da PIO de 24 horas e frequência de glaucoma em pacientes com síndrome da apnéia obstrutiva do sono
(2009-01-01)
Purpose: To determine the frequency of glaucoma and evaluate the behavior of 24-hour intraocular pressure in patients with the obstructive sleep apnea syndrome (OSAS). Methods: Eleven consecutive patients with OSAS, diagnosed ...
