Mechanisms for transient localization in a diatomic nonlinear chain

We investigate transient nonlinear localization, namely the self-excitation of energy bursts in an atomic lattice at finite temperature. As a basic...

Integrability, bilinearization, solitons and exact three wave solutionsfor a forced Korteweg-de Vries equation

The Korteweg-de Vries (KdV) equation with a forcing term is considered which demonstrates the mathematical modelling of the physics of a shallow la...

上海科技大学数学所助理教授岳海天在随机非线性薛定谔方程的研究上取得重要进展

随机非线性薛定谔方程是偏微分方程领域最近几十年最受关注和最有影响的研究方向之一。上海科技大学数学科学研究所助理教授岳海天与合作者在该方向取得了重要...

Solving the chaos model-data paradox in the cryptocurrency market

In this paper we test for nonlinearity and chaos in some cryptocurrencies returns and volatility. Financial markets are characterized by the so-cal...

Numerical study of the ternary Cahn-Hilliard fluids by using anefficient modified scalar auxiliary variable approach

Herein, we propose linear, decoupled, and energy dissipation-preserving schemes for the ternary Cahn-Hilliard (CH) fluid models by using a modified...

Fractional dynamics with non-local scaling

Nonlinear fractional dynamics with scale invariance in continuous and discrete time ap-proaches are described. We use non-integer-order integro-dif...

An algorithm to compute rotation intervals of circle maps *

In this article we present an efficient algorithm to compute rotation intervals of circle maps of degree one. It is based on the computation of the...
