Upcoming talk:
Title: Quantum Liouville theory
Speaker: Pengxiang Hao
Time: 11:30 am-1:30 pm (Beijing time), Nov.4th(Friday), 2022
Abstract: I will talk about the Liouville theory for itself, without referring to its origin. In particular, I will focus on the quantum aspect including the quantization, central charge, states, operators and correlation functions. A semi-classical picture will also be introduced.

Title: Introduction to the BFSS matrix theory
Speaker: Wenxin Lai
Time: 11:30 am-1:30 pm (Beijing time), Oct. 9th (Sunday), 2022
Abstract: In this talk, I will give a very brief introduction to the BFSS M(atrix) Theory and try to explore the motivation, evidence for this model as a first example of holographic duality. Refs: hep-th/9610043, hep-th/9510135
Title:Towards the non-perturbative cosmological bootstrap
Speaker: Reiko Liu
Time: 11:30 am-1:30 pm (Beijing time), Sep. 30th (Friday), 2022
Abstract: I'll talk about the properties of late-time correlators in dS spacetime, including the late-time expansion of bulk operators and the Källen-Lehmann spectral decomposition of two-point functions. Ref: 2107.13871
Title: Carrollian perspective on celestial CFT
Speaker: Xianjin Xie
Time: 11:30 am-1:30 pm (Beijing time), Sep. 16th (Friday), 2022
Abstract: The first goal is to show the same kinematic properties between 4d asymptotical spacetime and 3d sourced conformal Carrollian field theory(CCarrFT). Then show that the Ward identities of the sourced CCarrFT reproduce the BMS Ward identities of the celestial CFT after performing a certain integral transformations. Ref: 2202.04702
