An exponential growth condition in H^2 for the pullback attractor of a non-autonomous reaction-diffusion equation [PDF]
, 2001 Some exponential growth results for the pullback attractor of a reaction-diffusion when time goes to ÂĄ1 are proved in this paper. First, a general result about Lp\H1 0 exponential growth is established.

Existence of global attractor for a nonautonomous state-dependent delay differential equation of neuronal type [PDF]
, 2019 The analysis of the long-term behavior of the mathematical model of a neural network constitutes a suitable framework to develop new tools for the dynamical description of nonautonomous state-dependent delay equations (SDDEs).

Probabilistic continuity of a pullback random attractor in time-sample
Discrete & Continuous Dynamical Systems - B, 2020 Given a time-sample dependent attractor of a random dynamical system, we study its lower semi-continuity in probability along the time axis, and the criteria are established by using the local-sample asymptotically compactness for a triple-continuous ...

The Picard group in equivariant homotopy theory via stable module categories
Journal of Topology, Volume 18, Issue 2, June 2025.Abstract We develop a mechanism of âisotropy separation for compact objectsâ that explicitly describes an invertible G$G$âspectrum through its collection of geometric fixed points and gluing data located in certain variants of the stable module category.

The mean-square dichotomy spectrum and a bifurcation to a mean-square attractor [PDF]
, 2014 The dichotomy spectrum is introduced for linear mean-square random dynamical systems, and it is shown that for finite-dimensional mean-field stochastic differential equations, the dichotomy spectrum consists of finitely many compact intervals. It is then

Pullback attractor for a dynamic boundary non-autonomous problem with Infinite Delay
, 2017 In this work we prove the existence of solution for a p-Laplacian non-autonomous problem with dynamic boundary and infinite delay. We ensure the existence of pullback attractor for the multivalued process associated to the non-autonomous problem we are ...

Chemostat models with Monod and Haldane consumption functions and random environmental fluctuations
Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7412-7431, 15 May 2025.In this paper, we study the asymptotic dynamics of two chemostat models with random environmental fluctuations modeled by means of real noise, where different consumption functions for the consumer species (Monod and Haldane) are taking into account. For each model, our main goal is to investigate the existence of deterministic attracting sets.

Learning Metric Fields for Fast LowâDistortion Mesh Parameterizations
Computer Graphics Forum, Volume 44, Issue 2, May 2025.Abstract We present a fast and robust method for computing an injective parameterization with low isometric distortion for diskâlike triangular meshes. Harmonic functionâbased methods, with their rich mathematical foundation, are widely used. Harmonic maps are particularly valuable for ensuring injectivity under certain boundary conditions. In addition,
