英文摘要	In this work we consider AdS(3) gravitational theory with certain mixed boundary conditions at infinity. Using the Chem-Simons formalism of AdS(3) gravity, we find that these mixed boundary conditions lead to nontrivial boundary terms, which, in turn, produce exactly the spectrum of the T (T) over bar /J (T) over bar -deformed conformal field theories (CFTs). We then follow the procedure for constructing asymptotic boundary dynamics of AdS(3) to derive the constrained T (T) over bar -deformed Wess-Zumino-Witten (WZW) model from Chern-Simons gravity. The resulting theory turns out to be the T (T) over bar -deformed Alekseev-Shatashvili action after disentangling the constraints. Furthermore, by adding a U(1) gauge field associated to the current J, we obtain one type of the J (T) over bar -deformed WZW model, and show that its action can also be constructed from the gravity side. These results provide a check on the correspondence between the T (T) over bar /J (T) over bar -deformed CFTs and the deformations of boundary conditions of AdS(3), the latter of which may be regarded as coordinate transformations.
