• Place:  129-104 (SNU)   
• Speaker:  안창현 (경북대학교)

• TiTle:  w_{1+infty} algebra in the celestial holography

• Abstract: The outline of my talk is as follows.

1. Introduction,

2. IR structure of gravity, 

3. From the four dimensional gravity to the celestial conformal field theory in two dimensions,

4. Celestial amplitudes and celestial OPEs,

5. Soft symmetries, and 6. Q&A.

The general relativity and the particle physics at the undergraduate level can be very useful to understand my talk.
