Geometric and measure-theoretical structures of maps with mostly contracting center
Dmitry Dolgopyat, Marcelo Viana, Jiagang Yang
We show that every diffeomorphism with mostly contracting center direction exhibits a geometric-combinatorial structure, which we call \emph{skeleton}, that determines the number,…
Information-Entropic Measure of Energy-Degenerate Kinks in Two-Field Models
R. A. C. Correa, A. de Souza Dutra, M. Gleiser
We investigate the existence and properties of kink-like solitons in a class of models with two interacting scalar fields. In particular, we focus on models that display both doubl…
Investigating the interplay between mechanisms of anomalous diffusion via fractional Brownian walks on a comb-like structure
H. V. Ribeiro, A. A. Tateishi, L. G. A. Alves +2
The comb model is a simplified description for anomalous diffusion under geometric constraints. It represents particles spreading out in a two-dimensional space where the motions i…
Sample variance in N--body simulations and impact on tomographic shear predictions
Luciano Casarini, Oliver Piattella, Silvio Bonometto +1
We study the effects of sample variance in N--body simulations, as a function of the size of the simulation box, namely in connection with predictions on tomographic shear spectra.…
Empirical analysis on the connection between power-law distributions and allometries for urban indicators
Luiz G. A. Alves, Haroldo V. Ribeiro, Ervin K. Lenzi +1
We report on the existing connection between power-law distributions and allometries. As it was first reported in [PLoS ONE 7, e40393 (2012)] for the relationship between homicides…
High Spatial Resolution of the Mid-Infrared Emission of Compton-Thick Seyfert 2 Galaxy Mrk3
Dinalva A. Sales, D. Ruschel-Dutra, M. G. Pastoriza +2
Mid-infrared (MIR) spectra observed with Gemini/Michelle were used to study the nuclear region of the Compton-thick Seyfert 2 (Sy 2) galaxy Mrk 3 at a spatial resolution of 2…
