Title TTbar, Massive Gravity and Non-critical Strings
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.
