On the Dynamics of New 4D and 6D Hyperchaotic Systems

open access: yesMathematics, 2022
One of the most interesting problems is the investigation of the boundaries of chaotic or hyperchaotic systems. In addition to estimating the Lyapunov and Hausdorff dimensions, it can be applied in chaos control and chaos synchronization.

Large solutions of a class of degenerate equations associated with infinity Laplacian

open access: yesAdvanced Nonlinear Studies, 2022
In this article, we investigate the boundary blow-up problem Δ∞hu=f(x,u),inΩ,u=∞,on∂Ω,\left\{\begin{array}{ll}{\Delta }_{\infty }^{h}u=f\left(x,u),& {\rm{in}}\hspace{0.33em}\Omega ,\\ u=\infty ,& {\rm{on}}\hspace{0.33em}\partial \Omega ,\end{array}\right.

Backward Stochastic Differential Equations Driven by a Jump Markov Process with Continuous and Non-Necessary Continuous Generators

open access: yesFractal and Fractional, 2022
We deal with backward stochastic differential equations driven by a pure jump Markov process and an independent Brownian motion (BSDEJs for short). We start by proving the existence and uniqueness of the solutions for this type of equation and present a ...

Motion by crystalline-like mean curvature: A survey

open access: yesBulletin of Mathematical Sciences, 2022
We consider a class of anisotropic curvature flows called crystalline curvature flows. We present a survey on this class of flows with special emphasis on the well-posedness of its initial value problem.

Multimodal electromechanical model of piezoelectric transformers by Hamilton's principle [PDF]

open access: yes, 2009
This work deals with a general energetic approach to establish an accurate electromechanical model of a piezoelectric transformer (PT). Hamilton’s principle is used to obtain the equations of motion for free vibrations. The modal characteristics (mass,

A Liouville comparison principle for solutions of quasilinear singular parabolic inequalities

open access: yesAdvances in Nonlinear Analysis, 2015
We obtain a Liouville comparison principle for entire weak solutions (u,v) of quasilinear singular parabolic second-order partial differential inequalities of the form ut-A(u)-|u|q-1u≥vt-A(v)-|v|q-1v${ u_t - A(u)-|u|^{q-1}u \ge v_t - A (v)-|v|^{q-1}v ...

Exponential Synchronization of Partially Coupled Heterogeneous Networks With Time-Delays and Heterogeneous Impulsess

open access: yesIEEE Access, 2021
This work focuses on exponential synchronization for a class of partially coupled heterogeneous networks with time-delays and heterogeneous impulses. The synchronization targets are selected as the common equilibrium solution and the average trajectory ...

The Pigou-Dalton Principle and the Structure of Distributive Justice [PDF]

open access: yes, 2013
The Pigou-Dalton (PD) principle recommends a non-leaky, non-rank-switching transfer of goods from someone with more goods to someone with less. This Article defends the PD principle as an aspect of distributive justice --- enabling the comparison of two ...

Quasi-classical Molecular Dynamics Simulations of the Electron Gas: Dynamic properties [PDF]

open access: yes, 1997
Results of quasi-classical molecular dynamics simulations of the quantum electron gas are reported. Quantum effects corresponding to the Pauli and the Heisenberg principle are modeled by an effective momentum-dependent Hamiltonian.
