Vortex motion for the lake equations

open access: yes, 2020
The lake equations $$\left\{\begin{aligned} \nabla \cdot \big( b \, \mathbf{u}\big) &= 0 & & \text{on}\ \mathbb{R}\times D,\\ \partial_t\mathbf{u} + (\mathbf{u}\cdot \nabla)\mathbf{u} &= -\nabla h & & \text{on}\ \mathbb{R}\times D ,\\ \mathbf{u ...

Singular recursive utility

open access: yes, 2017
We introduce the concept of singular recursive utility. This leads to a kind of singular BSDE which, to the best of our knowledge, has not been studied before.

Convolutive decomposition and fast summation methods for discrete-velocity approximations of the Boltzmann equation

open access: yes, 2012
Discrete-velocity approximations represent a popular way for computing the Boltzmann collision operator. The direct numerical evaluation of such methods involve a prohibitive cost, typically $O(N^{2d+1})$ where $d$ is the dimension of the velocity space.

Stability of Caputa– Hadmmard  Fractional Differential Nonlinear ControlSystem with Delay Riemann −Katugampola

open access: yesWasit Journal for Pure Sciences
This research examines the finite-time stability of a specific category of neural networks with fractional order. Using modified Gronwall inequality and estimations of Mittag–Leffler functions, we provide adequate requirements to guarantee the finite ...

Finite-Time Stability of Neutral Fractional Time-Delay Systems via Generalized Gronwalls Inequality

open access: yesAbstract and Applied Analysis, 2014
This paper studies the finite-time stability of neutral fractional time-delay systems. With the generalized Gronwall inequality, sufficient conditions of the finite-time stability are obtained for the particular class of neutral fractional time-delay ...

Mean-Field Dynamics: Singular Potentials and Rate of Convergence [PDF]

open access: yes, 2018
We consider the time evolution of a system of N identical bosons whose interaction potential is rescaled by N −1. We choose the initial wave function to describe a condensate in which all particles are in the same one-particle state.

Analysis of a chemotaxis system modeling ant foraging

open access: yes, 2015
In this paper we analyze a system of PDEs recently introduced in [P. Amorim, {\it Modeling ant foraging: a {chemotaxis} approach with pheromones and trail formation}], in order to describe the dynamics of ant foraging.

Sharp Gronwall-Bellman type integral inequalities with delay

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
Various attempts have been made to give an upper bound for the solutions of the delayed version of the Gronwall-Bellman integral inequality, but the obtained estimations are not sharp.
