ITMP Seminar "The Giant Graviton Expansion from Bubbling Geometry"

ITMP Seminar
30 октября 2024

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Oct 30, 18:00 (Moscow time). It will be organised via Zoom. 

Speaker: Evan Deddo, University of Michigan

Title: The Giant Graviton Expansion from Bubbling Geometry

Abstract: The superconformal index of half-BPS states in N=4 supersymmetric Yang-Mills admits an expansion in terms of giant gravitons in the bulk description. The expansion can be viewed as the implementation of trace relations for finite N. I will demonstrate how to derive this expansion directly in type IIB supergravity from the class of half-BPS solutions due to Lin, Lunin, and Maldacena. The moduli space of these configurations can be quantized using covariant quantization methods. I will show how this quantization leads to the precise expression for the expansion in terms of giant gravitons. Our proposal provides a derivation of the expansion directly in terms of quantized supergravity degrees of freedom.

If you want to join the seminar please register here before 18:00, October 30 here.
