"Gravitational initial data:
 What happens when the free extrinsic curvature is scaled up"
 
 Professor O Murchadha, Niall
 University College Cork, Ireland
 
 Abstract: The standard way of solving he Einstein constraints in the 
 asymptotically flat case is to specify a 3-geometry and a TT tensor on it. 
 One then finds a conformal factor which maps to a solution of the 
 constraints. What happens if we scale up the TT tensor? The conformal 
 factor increases in a way that the ADM mass becomes large while the 
 physical extrinsic curvature decreases.

 "Tests of general relativity in the Advanced Detector Era"
 
 Professor Li, Tjonnie G.F. (黎冠峰)
 The Chinese University of Hong Kong, Hong Kong
 
 Abstract: The detection of GW150914, the gravitational-wave signal of the 
 merger of two black holes, by the Advanced LIGO detectors has opened the 
 possibility to probe the strong field regime of gravity for the first 
 time. I will discuss the latest results on the verifications of the 
 predictions of general relativity done by the LIGO-Virgo Collaboration.
