Because of the influence of Covid19, the usual JGRG workshop of this year had been postponed. JGRG is a valuable opportunity not only to provide young researchers with the place for presentations but also for researchers from various fields to meet and discuss together. Losing such opportunities is a huge disadvantage to our community. Therefore, we decided to hold an online workshop in place of the normal JGRG workshop.

We hope this online workshop provides a place where people can exchange ideas and pursue future trends of research. The workshop will cover a wide area of research related to general relativity and gravitation.

Workshop Dates: November 23 - 27, 2020 (online reception on 22th Nov. )

Program (updated on 26th Nov, pdf version is here)
