Title |
Three-Dimensional Massive Gravity on de-Sitter Space and Black Holes at the Special Point | |||||
| Co-authors | ||||||||
|
Abstract |
We study three-dimensional massive gravity on de-Sitter background and discuss several interrelated properties: The appearance of an enhanced symmetry point at linearized level where the theory becomes partially massless; its absence at full nonlinear level, and its relation with the existence of static black hole solutions and their gravitational hair parameter. |

Title |
Critical Gravity Waves | |||||
| Co-authors | ||||||||
|
Abstract |
Critical Gravity theories in D dimensions are known to exhibit logarithmic modes, which are analogous to those that are present in the so-called Log-Gravity in D=3. These Log-modes were shown to be important to analyze the consistency of the model both at classical and at quantum level. Here, we discuss exact solutions to Critical Gravity that correspond to non-linear realizations of such logarithmic modes. We investigate other points of the parameter space at which similar solutions appear. |
