Abstract The derivative nonlinear Schrödinger (DNLS) equation can be derived as an amplitude equation via multiple scaling perturbation analysis for the description of the slowly varying envelope of an underlying oscillating and traveling wave packet in dispersive wave systems. It appears in the degenerated situation when the cubic coefficient of the similarly derived NLS equation vanishes. It is the purpose of this paper to prove that the DNLS approximation makes correct predictions about the dynamics of the original system under rather weak assumptions on the original dispersive wave system if we assume that the initial conditions of the DNLS equation are analytic in a strip of the complex plane. The method is presented for a Klein–Gordon model with a cubic nonlinearity.
摘要通过多尺度摄动分析,可以将微分非线性Schrödinger (DNLS)方程导出为振幅方程,用于描述色散波系统中底层振荡和行波包的慢变化包络。当类似导出的NLS方程的三次系数消失时,出现退化情况。本文的目的是证明DNLS近似在原色散波系统较弱的假设下,如果假定DNLS方程的初始条件在复平面上是解析的,则DNLS近似能正确地预测原系统的动力学。针对具有三次非线性的Klein-Gordon模型,提出了该方法。

Abstract In this article, we study the inviscid limit of the stochastic incompressible Navier–Stokes equations in three-dimensional space. We prove that a subsequence of weak martingale solutions of the stochastic incompressible Navier–Stokes equations converges strongly to a weak martingale solution of the stochastic incompressible Euler equations in the periodic domain under the well-accepted hypothesis, namely Kolmogorov hypothesis ( K41 ).

Abstract Bresse system over the interval (0, L ) with pointwise dissipation at $$xi in (0,{L})$$ ξ ( 0 , L ) is analyzed. The exponential stability of the related semigroup is shown provided the dissipative points are of the form $$xi in mathbb {Q}{L}$$ ξ Q L and $$xi ne frac{n}{2m+1}L$$ ξ n 2 m + 1 L , where $$n,min mathbb {N}$$ n , m N and n , and $$2m+1$$ 2 m + 1 are co-prime.

Dynamical analysis of an age-space structured malaria epidemic model 年龄空间结构疟疾流行模型的动力学分析

Abstract In this paper, we will revisit the model studied in Lou and Zhao (J Math Biol 62:543–568, 2011), where the model takes the form of a nonlocal and time-delayed reaction–diffusion model arising from the fixed incubation period. We consider the infection age to be a continuous variable but without the limitation of the fixed incubation period, leading to an age-space structured malaria model in a bounded domain. By performing the elementary analysis, we investigate the well-posedness of the model by proving the global existence of the solution, define the explicit formula of basic reproduction number when all parameters remain constant. By analyzing the characteristic equations and designing suitable Lyapunov functions, we also establish the threshold dynamics of the constant disease-free and positive equilibria. Our theoretical results are also validated by numerical simulations for 1-dimensional and 2-dimensional domains.
在本文中,我们将重新审视Lou和Zhao (J Math Biol 62:543-568, 2011)所研究的模型,该模型采用由固定潜伏期引起的非局部延时反应扩散模型的形式。我们认为感染年龄是一个连续变量,但不受固定潜伏期的限制,从而在有界域中得到年龄空间结构的疟疾模型。通过初步分析,通过证明解的整体存在性,研究了模型的适定性,定义了所有参数保持不变时基本再现数的显式公式。通过分析特征方程和设计合适的Lyapunov函数,建立了常无病平衡点和正平衡点的阈值动力学。我们的理论结果也通过一维和二维的数值模拟得到了验证。
