Estimadores do tipo núcleo para a densidade de transição de uma cadeia de markov com espaço de estados geral
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Matemática Aplicada e EstatísticaProbabilidade e Estatística; Modelagem Matemática, 2010-05-21)
In this work, we studied the strong consistency for a class of estimates for a transition density of a Markov chain with general state space E ⊂ Rd. The strong ergodicity of the estimates for the density transition is ...

Billiards in a General Domain with Random Reflections
(SPRINGER, 2009)
We study stochastic billiards on general tables: a particle moves according to its constant velocity inside some domain D R(d) until it hits the boundary and bounces randomly inside, according to some reflection law. We ...
Structure of distributions generated by the scenery flow
(Wiley, 2015-01)
We expand the ergodic theory developed by Furstenberg and Hochman on dynamical systems that are obtained from magnifications of measures. We prove that any fractal distribution (FD) in the sense of Hochman is generated by ...
Finite rank Bratteli-Vershik diagrams are expansive
(2008)
The representation of Cantor minimal systems by Bratteli–Vershik diagrams has been extensively used to study particular aspects of their dynamics. A main role has been played by the symbolic factors induced by the way ...
Finite-rank Bratteli-Vershik diagrams are expansive
(CAMBRIDGE UNIV PRESS, 2008-06)
The representation of Cantor minimal systems by Bratteli-Vershik diagrams has been extensively used to study particular aspects of their dynamics. A main role has been played by the symbolic factors induced by the way ...
QUALITATIVE PROPERTIES OF NONLINEAR PARABOLIC EQUATIONS WITH DOMINATING GRADIENT TERMSPROPIEDADES CUALITATIVAS DE ECUACIONES PARABOLICAS NO-LINEALES CON TÉRMINOS GRADIENTE DOMINANTESQualitative properties of nonlinear parabolic equatións with dominating gradient termspropiedades cualitativas de ecuaciónes parabolicas no-lineales con términos gradiente dominantes
(2018)
My thesis consists of contributions to the study of viscosity solutions of nonlinear parabolic equations. We address the phenomena of continuous solvability, loss of boundary conditions, and the large-time behavior for ...
Emergence of very long time fluctuations and 1/f noise in ideal flows
(American Physical Society, 2011-06)
This paper shows the connection between three previously observed but seemingly unrelated phenomena in hydrodynamic (HD) and magnetohydrodynamic (MHD) turbulent flows, involving the emergence of fluctuations occurring on ...
