### Director's Seminar

#### [IBS-CGP Seminar]

#### January 31, 2018 –

#### CGP Main Hall

The purpose of this seminar is to give updates on current developments and mathematical research highlights in general to CGP members and visitors, and to promote deeper interaction between the speaker and the audience. The seminar's general spirit reflects that of the famous Gelfand Seminar.
