Abstract |
I will argue that the natural gravitational picture of the TTbar deformation is ghost-free massive gravity,
showing that massive gravity naturally emerges as an appropriately defined version of the random geometries
framework. The important role of field dependent diffs is just a straightforward consequence of the
Stuckelberg formalism of massive gravity. I will discuss these various connections, how (non)-critical strings
arise naturally as the deformation of CFTs, and how to give path integral definitions for more general
deformations. |
