DESCRIPTION:TTbar-deformed theories provide a unique perspective on both Q
 FT\, beyond the Wilsonian paradigm\, and on holography\, beyond the standa
 rd asymptotic boundary conditions. To understand how these theories are or
 ganized\, I will discuss their locality structure through the infinite-dim
 ensional field-dependent symmetries\, which they inherit from the conforma
 l group. Analyzing the symmetry generators both semi-classically and as qu
 antum operators\, we find that these theories are quasi-local and contain 
 free parameters\, revealing potential ambiguities in the Hamiltonian formu
 lation. I will discuss some of the implications for the holographic interp
 retation and illustrate with an example where everything can be calculated
  explicitly at the semi-classical level\, thus providing a litmus test for
  different proposals in the literature.
