DESCRIPTION:Abstract\n\nThe T\\barT deformation can be formulated as a dy
namical change of coordinates. We establish and generalize this relation t
o curved spaces by coupling the undeformed theory to 2d gravity. For curve
d space the dynamical change of coordinates is supplemented by a dynamical
Weyl transformation. We also sharpen the holographic correspondence to cu
toff AdS33 in multiple ways. First\, we show that the action of the an
nular region between the cutoff surface and the boundary of AdS33 is g
iven precisely by the T\\barT operator integrated over either the cutoff
surface or the asymptotic boundary. Then we derive dynamical coordinate a
nd Weyl transformations directly from the bulk. Finally\, we reproduce the
flow equation for the deformed stress tensor from the cutoff geometry.\n\
