The 21st workshop on General Relativity and Gravitation in Japan (JGRG21)

Sakura Hall, Katahira Campus, Tohoku University
26-29 September 2011

There has been an impressive progress in astrophysical/cosmological observations in recent years. Cosmology has entered an era of precision science. Astrophysical black holes have been observed in many frequency bands with better resolutions and sensitivities. Observations of gamma-ray bursts have added a new mystery to relativistic astrophysics. And, a new frontier is waiting to be explored by gravitational wave interferometers. On the theoretical side, motivated by unified theories of fundamental interactions, especially string theory, many efforts have been made for studies of physics in 5-dimensional or higher dimensional spacetimes, and there is a growing interest in experimental verifications of extra dimensions. There have been also important and interesting developments in various other areas, including alternative theories of gravity, quantum gravity, and spacetime singularities, to mention a few. In this workshop, we plan to overview these recent developments and discuss future perspectives through invited and contributed presentations.

The 20th conference on general relativity and gravitation in Japan (JGRG20)

About JGRG20 conference

The 20th conference on general relativity and gravitation in Japan (JGRG20) will be held from September 21 to 25, 2010, at Yukawa Institute for Theoretical Physics, Kyoto University. The information is available at http://www2.yukawa.kyoto-u.ac.jp/~jgrg20/. The webpage includes (partial) information of invited speakers and a link to register and submit a possible contributed presentation. The site will be updated shortly with the final list of speakers.

Takashi Nakamura and Kei-ichi Maeda, who have been the primary organizers of the JGRGs, will be 60 years old in September and October 2010, respectively. We are going to celebrate their 60th birthday in JGRG20.
