On time-dependent wave propagation in shadow zones caused by the inhomogeneity of the medium
Abstract
The symmetric orbifold of ${\mathbb{T}}^{4}$ is the CFT dual of string theory on ${\mathrm{A}\mathrm{D}\mathrm{S}}_{3}{\times}{\mathrm{S}}^{3}{\times}{\mathbb{T}}^{4}$ with minimal NS-NS flux. We study its symmetry algebra and provide evidence that it does not have any deformation parameter. This suggests that the symmetric orbifold is (at least locally) the most symmetrical CFT in its moduli space.
