Journal club seminar: The spectrum of Laplacian on moduli space via Liouville theory

Title: The spectrum of Laplacian on moduli space via Liouville theory

Abstract: We are going to discuss the nice talk by Sarah Harrison  on String Math 2020 conference "The spectrum on M_{0,4} via Liouville theory". Slava Lysov will lead the discussion. 

Journal club seminar: Conformal higher spin gauge models in curved backgrounds

Title: Conformal higher spin gauge models in curved background

Speakers: Sergei Kuzenko and Michael Ponds

Abstract: Sergei Kuzenko and Michael Ponds from The University of Western Australia will tell us about conformal higher spin gauge models in curved background. The talk is based on their two recent papers   "Generalised conformal higher-spin fields in curved backgrounds" and  "New locally (super)conformal gauge models in Bach-flat backgrounds". 

QG Group meeting: D-branes of higher-spin gravity?

QG group meeting.
Speaker: Yasha Neiman.
Title: "D-branes of higher-spin gravity?"

Journal club seminar: A short review of N=2 SUSY Quantum Mechanics

Title:A short review of N=2 SUSY Quantum Mechanics

Abstract: We are going to SUSY Quantum Mechanics. The good review of the subject is a paper by F. Cooper, A. Khare, U. Sukhatme   "Supersymmetry and Quantum Mechanics". Mirian Tsulaia will lead the discussion. 

QG group meeting: Symplectic Reduction in Field Theory

Title: Symplectic Reduction in Field Theory

Speaker: Slava Lysov

Abstract: We will briefly review the symplectic recution in finite dimensional case and generalization to the field theory with possible inclusion of the edge modes. We will apply these ideas to the  BF-model and compare the results with the predictions of algebraic topology.

Abstract: We are going to discuss String Theory conference talk by J. Maldacena   "Review: Recent progress on the black hole information paradox". Slava Lysov will lead the discussion. 

Group Meeting Talk: Current Algebras and Celestial CFT Correlators

Title: Current Algebras and Celestial CFT Correlators

Speaker: Sudip Ghosh

Abstract: I will discuss the construction of a SL(2,C) current algebra using the subleading soft graviton theorem and the constraints imposed by this current algebra via null state relations on the spectrum of the putative CFT dual of Einstein gravity in (3+1)-d asymptotically flat spacetimes.
