| 英文摘要 | The T (T) over bar deformed 2D CFTs correspond to AdS(3) gravity with Dirichlet boundary condition at finite cutoff or equivalently a mixed boundary condition at spatial infinity. In this work, we use the latter perspective and Chern-Simons formalism of AdS(3) gravity to construct the surface charges and associated algebra in T (T) over bar deformed theories. Starting from the Banados geometry, we obtain the Chern-Simons gauge fields for the T (T) over bar deformed geometry, which are parametrized by two independent charges. With help of the mixed boundary condition, the residual gauge symmetries of the deformed gauge fields and the associated surface charges were obtained respectively. The charge algebra turns out to be a non-linear deformed Virasoro algebra, which was obtained in different way by applying the cutoff perspective. Finally, we propose a way to construct the time-independent charges from these surface charges and they satisfy the field-dependent Virasoro algebra. |
