Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rigidity results in mapping class groups and homeomorphism groups
映射类群 同胚群 刚性结果
2023/11/13
Mapping class groups and homeomorphism groups are symmetry groups of surfaces and all manifolds. They are usually very rigid, in the sense that their automorphism groups only consist of conjugation. I...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Deformation rigidity of Fano manifolds
法诺歧管 变形刚度 光滑射影品种X
2023/4/17
A smooth projective variety X is called rigid if any deformation of X is isomorphic to itself. A first example is the projective space, but in general it is a subtle and difficult problem to prove the...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Spectral rigidity and joint integrability for Anosov diffeomorphisms on tori
环形 阿诺索夫微分同胚 谱刚度 联合可积性
2023/4/14
In this talk, we address on the strong rigidity properties from joint integrability in the setting of Anosov diffeomorphisms on tori. More specifically, for an irreducible Anosov diffeomorphism with s...
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...

The superrigidity theorem of Margulis, see Zimmer [17], classifies finite dimen-sional representations of lattices in semi-simple Lie groups of real rank strictly
larger than 1. It is a fundamental ...
The evidence for the existence of significant rigidity in the Earth's inner core is summarised and discussed in the light of recent work. Quantum-mechanical calculations, based on a Thomas-Fermi-Dirac...

Rigidity Cinema Seen Front Row Side Aisle
2015/8/13
Pictures and cinema seen at a slant present the optics of virtual objects that are distorted and incon-sistent with their real counterparts. In particular, it should not be possible for moving objects...
Comments on ‘Wage Rigidity and Unemployment in OECD Countries’ by D. Grubb, R. Jackman and R. Layard
Wage Rigidity Unemployment
2015/8/4
Econometric investigations of individual countries’ experiences with inflation
and unemployment in the 1970’s have shown that it is no longer sufficient to
simply assume that wages are sticky in ord...
Problems in Generic Combinatorial Rigidity: Sparsity, Sliders, and Emergence of Components
Algorithms Geometry Graph Theory Matroids Random Graphs Rigidity Theory
2014/12/18
Rigidity theory deals in problems of the following form: given a structure defined by geometric constraints on a set of objects, what information about its geometric behavior is implied by the underly...
Towards Large-Scale Validation of Protein Flexibility Using Rigidity Analysis
flexibility protein rigidity analysis validation
2014/12/18
Proteins are dynamic molecules involved in virtually every chemical process in our bodies. Understanding how they flex and bend provides fundamental insights to their functions. At the atomic level, p...
Effects of blade flexural rigidity on drag force and mass transfer rates in model blades
blade flexural rigidity model blades
2014/11/28
We created a model physical system to investigate the role of blade rigidity in setting forces and rates of mass
exchange for a blade exposed to unsteady flow in a vortex street. Using a combination ...

Where Do We Draw Our Lines Approach/Avoidance Motivation Political Orientation Cognitive Rigidity
2014/10/28
Rigidity has been widely studied by many subdisciplines of psychology, including personality, social, cognitive, developmental, educational, neuropsychology, organizational behavior, psychopathology a...

RIGIDITY OF STATIONARY BLACK HOLES SMALL ANGULAR MOMENTUM THE HORIZON
2014/4/3
We prove a black hole rigidity result for slowly rotating stationary solutions of the Einstein vacuum equations. More precisely, we prove that the domain of outer communications of a regular stationar...
Influence of Shear Rigidity of Main and Flooring Ledger Frames on the Strength of Simple Prefabricated Scaffolds
Shear Rigidity Main Flooring Ledger Frames Strength Simple Prefabricated Scaffolds
2013/9/30
The presumption method was established to examine the compressive strength of one main frame in order to evaluate the strength of standard prefabricated scaffolds, which in turn is determined by the d...

stationary black holes horizon
2014/4/3
In collaboration with S. Alexakis and A. Ionescu we prove that the domain of outer communications of a regular stationary vacuum is isometric to the domain of outer communications of a Kerr solution, ...
