Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rigidity of non-compact static domains in hyperbolic space via positive mass theorems
正质量定理 双曲空间 非紧致 静域刚性
2023/4/14
We single out a notion of staticity which applies to any domain in hyperbolic space whose boundary is a non-compact totally umbilical hypersurface. For (time-symmetric) initial data sets modeled at in...

Optimal linear static control with moment and yield objectives
Linear static control gaussian distribution convex optimization
2015/8/11
This report describes how to optimize linear static control problems involving first and second moments and yield objectives for Gaussian distributions. These problems can be cast as second-order cone...
Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
ODE Voltage Collapse Feeder Line Power Flows Static Disorder
2011/7/6
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however, voltage anywhere further down ...
Among all electromagnetic theories which (a) are derivable from a Lagrangian, (b) satisfy the
dominant energy condition, and (c) in the weak eld limit coincide with classical linear electromagnetics...

With development in communication and information technology and fast distribution of personal computers, the use of technology in training has improved. The foundation of mathematics educational fiel...
Absence of ground state for the Nelson model on static space-times
Quantum field theory Nelson model static space-times ground state
2011/1/21
We consider the Nelson model on some static space-times and investigate the problem of absence of a ground state. Nelson models with variable coefficients arise when one replaces in the usual Nelson m...
Static two-grid mixed finite-element approximations to the Navier-Stokes equations
Static two-grid mixed finite-element the Navier-Stokes equations
2010/11/19
A two-grid scheme based on mixed finite-element approximations to the incompressible Navier-Stokes equations is introduced and analyzed. In the first level the standard mixed finite-element approxima...
Robust Transceiver Design for K-Pairs Quasi-Static MIMO Interference Channels via Semi-Definite Relaxation
K-Pairs Quasi-Static MIMO Interference Channels Semi-Definite Relaxation
2010/12/9
In this paper, we propose a robust transceiver design for the K-pair quasi-static MIMO interference channel. Each transmitter is equipped with M antennas, each receiver is
equipped with N antennas.
An SKT metric is an Hermitian metric on a complex manifold whose fundamental 2-form ! satisfies @@! = 0. Streets and Tian introduced in [STb] a Ricci-type flow that preserves
the SKT condition.
Nonlocal Phases of Local Quantum Mechanical Wavefunctions in Static and Time-Dependent Aharonov-Bohm Experiments
Nonlocal Phases Local Quantum Mechanical Wavefunctions Static
2010/12/15
We show that the standard Dirac phase factor is not the only solution of the gauge ransformation equations. The full form of a general gauge function (that connects systems that move in different sets...
Adaptive financial networks with static and dynamic thresholds
financial networks static dynamic thresholds
2010/4/27
Based on the daily data of American and Chinese stock markets, the dynamic behavior of a financial network with static and dynamic thresholds is investigated. Compared with the static threshold, the d...

direct integration technique. Using the above men...
Cauchy-Born Rule and the Stability of Crystalline Solids: Static Problems
Atomistic models of solids nonlinear elasticity Cauchy-Born rule stability of crystals
2012/8/1
We study the connection between atomistic and continuum models for the elastic deformation of crystalline solids at zero temperature. We prove, under certain sharp stability conditions, that the corre...
