Perturbative anomalous exponents from Kolmogorov multipliers
Alexei A. Mailybaev, Simon Thalabard
Intermittency, manifested through anomalous scaling, remains one of the central unresolved problems in turbulence theory, with few analytical approaches extending beyond idealized…
Distributional and mean Li-Yorke chaos for weighted shifts on Fréchet sequence spaces
João V. A. Pinto
In this paper, we give characterizations of distributional chaos and mean LiYorke chaos for weighted backward shifts acting on general Fréchet sequence spaces. As an application…
Algebraic correspondences and Schwarz reflections: Where rational dynamics meets Kleinian groups
Luna Lomonaco, Sabyasachi Mukherjee
We present an overview of the rapidly evolving field of dynamics of algebraic correspondences, with a focus on matings between rational maps and Kleinian groups. These corresponden…
Precipitation nowcasting of satellite data using physically-aligned neural networks
Antônio Catão, Melvin Poveda, Leonardo Voltarelli +1
Accurate short-term precipitation forecasts predominantly rely on dense weather-radar networks, limiting operational value in places most exposed to climate extremes. We present TU…
Geometric implicit neural representations for signed distance functions
Luiz Schirmer, Tiago Novello, Vinícius da Silva +5
\textit{Implicit neural representations} (INRs) have emerged as a promising framework for representing signals in low-dimensional spaces. This survey reviews the existing literatur…
From Volume Rendering to 3D Gaussian Splatting: Theory and Applications
Vitor Pereira Matias, Daniel Perazzo, Vinicius Silva +4
The problem of 3D reconstruction from posed images is undergoing a fundamental transformation, driven by continuous advances in 3D Gaussian Splatting (3DGS). By modeling scenes exp…
