DESCRIPTION:TTbar-deformed theories provide a unique perspecti
 ve on both QFT\, beyond the Wilsonian paradigm\, a
 nd on holography\, beyond the standard asymptotic 
 boundary conditions. To understand how these theor
 ies are organized\, I will discuss their locality 
 structure through the infinite-dimensional field-d
 ependent symmetries\, which they inherit from the 
 conformal group. Analyzing the symmetry generators
  both semi-classically and as quantum operators\, 
 we find that these theories are quasi-local and co
 ntain free parameters\, revealing potential ambigu
 ities in the Hamiltonian formulation. I will discu
 ss some of the implications for the holographic in
 terpretation and illustrate with an example where 
 everything can be calculated explicitly at the sem
 i-classical level\, thus providing a litmus test f
 or different proposals in the literature.
