Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：ANALYSIS AND APPROXIMATION OF FLUIDS UNDER SINGULAR FORCING
奇异强迫体 分析 近似 牛顿流体
2023/5/5
Motivated by applications, like modeling of thin structures immersed in a fluid, we develop a well posedness theory for Newtonian and some non-Newtonian fluids under singular forcing in Lipschitz doma...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The long wave approximation of the Green-Naghdi equations with the Coriolis effect
格林-纳格迪方程 长波近似 科里奥利效应
2023/5/8
This talk study the long wave asymptotic behavior of Green-Naghdi equations, which could be used to describe the propagation of long-crested shallow-water waves in the equatorial ocean regions with th...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Diffusion limit of the compressible Euler-P1 approximation model arising from radiation hydrodynamics
辐射流体动力学 可压缩欧拉 近似模型 扩散极限
2023/5/8
We first show the nonequilibrium-diffusion limit of the compressible Euler-P1 approximation model arising in radiation hydrodynamics as the Mach number tends to zero when the initial data is well-prep...

This paper presents a fnite element model for strain localization analysis of elastoplastic solids subjected to discontinuous displacement felds based on standard Galerkin approximation. Strain enhanc...
On deterministic approximation of the Boltzmann equation in a bounded domain
Boltzmann equation spectral methods asymptotic stability boundary values problem
2011/9/9
Abstract. In this paper we present a fully deterministic method for the numerical solution to the Boltzmann equation of rarefied gas dynamics in a bounded domain for multi-scale problems.Periodic, spe...
Comparison of the Fargue-type analytical approximation and the numerical semi-discretization method for delayed systems
parametric excitation time delay stability
2010/3/12
Stability of linear time periodic delay-di®erential equations is investigated. An analytical approximation, the so-called Fargue-type method, and a numerical approximation, the so-called semi-disc...
