| Abstract: After brief introduction, I will describe the IR structure of the gravity. From four dimensional gravity, I will explain how the two dimensional celestial conformal field theory arises. Then I will consider the celestial amplitudes and celestial OPEs with collinear limit. Moreover, I will present the soft symmetries in order to absorb the infinite number of divergences of the Euler beta function. Finally, I will show my recent works. Link to the Event Video |
