Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Spectral instability of Electronic Euler-Poisson System
电子 Euler-Poisson系统 谱不稳定性
2023/12/11
The focus of this presentation is the spectral (in-)stability of periodic waves for the electronic Euler-Poisson system, a hydrodynamical model for understanding electron dynamics in plasmas. It is fo...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Homological instability for the moduli space of smooth 4-manifolds
光滑 4-流形模空间 同调不稳定性
2023/5/5
The moduli space of a smooth manifold X is defined to be the classifying space of its diffeomorphism group. Understanding the cohomology group of this space is important because elements in this group...

跨音速稳态 非线性结构稳定性 线性动态不稳定性 半导体 流体动力学模型
2023/5/8
For unipolar hydrodynamic model of semiconductor device represented by Euler-Poisson equations, when the doping profile is supersonic, the existence of steady transonic shock solutions and C^\infty-sm...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Stability and instability of a generic non--conservative compressible two--fluid model
通用非保守 可压缩 双流体模型 稳定性 不稳定性
2023/5/8
We are concerned with stability and instability of the steady state (1,0, 1, 0) for a generic non–conservative compressible two–fluid model in R^3. Under the assumption that the initial fraction densi...
Trying to decipher all of the factors that influence the behavior of complex ecological communities can be a daunting task. However, MIT researchers have now shown that the behavior of these ecosystem...
Farmers' climate change conundrum: Low yields or revenue instability（图）
Farmers climate change conundrum Low yields revenue instability
2020/7/17
Climate change will leave some farmers with a difficult conundrum, according to a new study by researchers from Cornell University and Washington State University: risk more revenue volatility, o...
Antarctic ice cliffs may not contribute to ice-sheet instability as much as predicted（图）
Antarctic ice cliff contribute ice-sheet instability
2019/11/5
Antarctica's ice sheet spans close to twice the area of the contiguous United States. Its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid w...
Instability in Antarctic ice projected to increase likelihood of worst-case sea level rise（图）
Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...

Massive East Antarctic Ice Sheet Has History Of Instability（图）
East Antarctic Ice Sheet History Instability
2017/12/19
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, n...
