### CGP Seminar

#### [IBS-CGP Seminar]

#### May 29, 2013 –

#### CGP Main Hall

Center for Geometry and Physics (CGP) Seminars on every Thursday afternoon are the most important regular event of IBS-CGP, and all members of the center are expected to participate. The seminars are formatted to encourage robust and dynamic interactions among participants. The first part of the seminar is a scheduled 2-hour talk by a designated speaker starting at 2 pm with a 30-minute intermission with tea and snack. After the talk, there is a discussion session where an improvised talk by the original speaker or a participant may be organized on spot until 6 pm. Discussions may continue over dinner.
