Processo de Bernoulli correlacionado
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2019-06-28)
The independent Bernoulli process, which is a sequence of independent Bernoulli random variables, is already widely known in the statistical literature. This masters thesis works with a generalization of this process: the ...
The structure of MgII absorption systems from spectra of gravitationally lensed quasars
(Universidad de Chile, 2012)
In this thesis I present a search for MgII absorption systems in the resolved spectra of 10 high redshifts gravitationally lensed quasars. The goal of the thesis is to study the spatial structure of MgII systems. The quasars ...
Distribución asintótica de los estimadores MCO en una regresión lineal con variables explicativas que siguen procesos estocásticos strong-mixing y tendencia
(Universidad Nacional Mayor de San MarcosPE, 2018)
Trata de obtener la distribución asintótica de los estimadores de mínimos cuadrados ordinarios (MCO) en regresiones de series temporales con variables explicativas que siguen procesos estocásticos strong-mixing y tendencia. ...
Sistemas elípticos com pesos envolvendo o expoente crítico de Hardy-Sobolev
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Matemática - PPGM, 2007-11-20)
In this work, we will study the existence and nonexistence of positive weak solutions
for two classes of elliptic systems with weights. The first class will involve nonlinearities of
the type positone and semipositone. We ...
Existence and multiplicity of solutions for problems involving the Dirac operator
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2019-07-30)
In this thesis, we study equations that involving the Dirac operator and which have the form
$-i \alpha \cdot \nabla u + a \beta u + M(x)u = F_{u}(x,u), em \mathbb{R}^{3},$
where $\alpha = (\alpha_1, \alpha_2, \alpha_3),$ ...
