Variational Principles for Lie-Poisson and Hamilton-Poincaré Equations
(Independent Univ Moscow, 2003-07)
As is well-known, there is a variational principle for theEuler–Poincar ́e equations on a Lie algebragof a Lie groupGobtainedby reducing Hamilton’s principle onGby the action ofGby, say, leftmultiplication. The purpose of ...
Passeios e bilhares: Uma incursão em sistemas dinâmicos aleatórios
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAPrograma de Pós-Graduação em MatemáticaUFMG, 2021-04-14)
In the first part of the thesis, we work with the random walk in a random environment determined by a partially hyperbolic diffeomorphism. In this work, we found necessary and sufficient conditions for the existence of a ...
Medidas tipo-SRB y Fórmula de Pesin en Sistemas C 1 -Expansores
(UR.FC.CMAT, 2017)
Estudiaremos mapas expansores f de regularidad C 1 en una variedad Riemanniana compacta M de dimensión finita. Nuestro principal objetivo es demostrar que las medidas pseudo-físicas, tambien llamadas “tipo-SRB” (similares ...
Determinante regularizado do Laplaciano e conjuntos isoespectrais em superfícies
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2019-02-27)
On compact surfaces with boundary, with some conditions in a conformal class, we study the problem about to find a metric with constant Gaussian curvature with boundary of constant geodesic curvature for which the regularized ...
Interpolation of geometric structures compatible with a pseudo Riemannian metric
(Springer, 2016-11)
Let (M, g) be a pseudo Riemannian manifold. We consider four geometric structures on M compatible with g: two almost complex and two almost product structures satisfying additionally certain integrability conditions. For ...
