Joint Colloquium: Xiao Zhang -- Some Geometrical Problems in General Relativity Speaker: Prof. Xiao Zhang http://sourcedb.cas.cn/sourcedb_amss_cas/yw/rck/200907/t20090727_2266967.html Time: Friday, March 7, 2:30--3:30PM Room: Carslaw 175, the University of Sydney Lunch plan: we meet near Level 2 entrance to Carslaw Building around 1:30PM. The lunch would be at Law Annex Cafe at 1:40PM. ----------------------------------------------- Title: Some Geometrical Problems in General Relativity Abstract: There has been a natural connection between geometry and gravity since Einstein. In this talk, we will discuss some geometrical problems relating to the positivity of the total energy-momentum in general relativity . The unsolved problems on the collision and the nonlinear stability of black holes will also be discussed. ----------------------------------------------- Joint Colloquium web site: http://www.maths.usyd.edu.au/u/SemConf/JointColloquium/index.html
