Separatrizes de germes de campos de vetores analíticos reais em dimensão dois
(Universidade Federal de Minas GeraisBrasilICEX - INSTITUTO DE CIÊNCIAS EXATASPrograma de Pós-Graduação em MatemáticaUFMG, 2021-08-12)
This thesis is dedicated to the study of conditions to ensure the existence of formal separatrices for a foliation defined by a germ of real analytical vector field with an algebraically isolated singularity at the origin ...
Polarization squeezing and new states of light in quantum optics
(1994)
The concept of squeezing is discussed for multimode quantum light beams with the consideration of polarization using the polarization gauge SU (2) invariance of free electromagnetic fields. We separate the polarization ...
Folheações em P2 admitindo feixe linear polar redutível
(Universidade Federal de Minas GeraisUFMG, 2011-09-08)
Given a foliation F on P2 , by fixing a line L P2 C, we define the polar pencil of F with axis L as the set of all polar curves of F with respect to points l 2 L. We begin this thesis by studying foliations F which admit ...
INFERENCE FOR EIGENVALUES AND EIGENVECTORS OF GAUSSIAN SYMMETRIC MATRICES
(INST MATHEMATICAL STATISTICS, 2008)
This article presents maximum likelihood estimators (MLEs) and log-likelihood ratio (LLR) tests for the eigenvalues and eigenvectors of Gaussian random symmetric matrices of arbitrary dimension, where the observations are ...
The analysis of NMR J-couplings of saturated and unsaturated compounds by the localized second order polarization propagator approach method
(American Institute of Physics, 2012-05)
Calculations of NMR J-coupling with polarization propagators are not invariant under unitary transformations at second order level of approach, second order polarization propagator approach (SOPPA). They are only invariant ...
WEIGHTED HOMOGENEOUS MAP GERMS OF CORANK ONE FROM C ³ TO C ³ AND POLAR MULTIPLICITIES
(Universidad Católica del Norte, Departamento de Matemáticas, 2002)
A tunable mechanism to control photo-dissociation with invariant tori with variable energies
(2018-01-15)
In this work, we investigate the classical dynamics of a polar diatomic molecule under the action of a space and time-dependent laser field. In the absence of laser fields, the phase space consists of a bound and an unbound ...
Algorithms of Intrinsic Complexity for Point Searching in Compact Real Singular Hypersurfaces
(Springer, 2012-02)
For a real square-free multivariate polynomial F, we treat the general problem of finding real solutions of the equation F=0, provided that the real solution set {F=0}ℝ is compact. We allow that the equation F=0 may have ...
