Mixed discriminants
(Springer, 2013-08)
The mixed discriminant of n Laurent polynomials in n variables is the irreducible polynomial in the coefficients which vanishes whenever two of the roots coincide. The Cayley trick expresses the mixed discriminant as an ...
A family of maximal noncontrollable Lie wedges with empty interior

Complexo quadrático de retas
(Universidade Federal de Minas GeraisUFMG, 2007-04-16)
On studying the Grassmanian of lines in projective space and Plücker's Quadric related to it, we noted the presence of interesting congurations of lines. From those congurations, a surface in projective space, the so called ...
Thirring model with jump defect
(2009-12-01)
The purpose of our work is to extend the formulation of classical affine Toda Models in the presence of jump defects to pure fermionic Thirring model. As a first attempt we construct the Lagrangian of the Grassmanian ...

Quantum function algebras from finite-dimensional Nichols algebras
(European Mathematical Society, 2020-10)
We describe how to find quantum determinants and antipode formulas from braidedvector spaces using the FRT-construction and finite-dimensional Nichols algebras. It improvesthe construction of quantum function algebras using ...
Hipersuperfícies Levi-flat e webs holomorfas
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAPrograma de Pós-Graduação em MatemáticaUFMG, 2021-06-11)
In this thesis, aspects of the local and global theory of Holomorphic Webs and Levi-flat Hypersurfaces will be considered. We will address three proposals. The first one, is to consider a real analytic Levi-flat hypersurface ...
Os teoremas de Sturm e geometria simplética
(Universidade Federal de Minas GeraisUFMG, 2012-02-24)
We studied systems of non-autonomous ordinary differential equations of the form (B(t)x0)0 = A(t)x, x E Rn, in which the matrices A(t) e B(t) are symmetric for all t in reals, identifying them with equivalent hamiltonian ...
Determinación de un quiver Grassmanniano isomorfo a una curva proyectiva plana
(Universidad Nacional de TrujilloPE, 2021)
El presente trabajo de investigación se realizó con el fin de determinar un quiver Grassmanniano
isomorfismo a una curva proyectiva plana dada. Para ello, se presentó al
espacio proyectivo, sobre el cual se definió la ...
