Critical metrics and massive gravity solutions on three-dimensional Brinkmann waves
(IOPscience, 2022)[Abstract] Three-dimensional Brinkmann waves which are critical for quadratic curvature functionals are determined. Generically, if the metric is critical for some functional then it is critical for all of them. In contrast, ... -
Vacuum Einstein field equations in smooth metric measure spaces: the isotropic case
(IOPscience, 2022)[Abstract] On a smooth metric measure spacetime (M, g, e−fdvolg), we define a weighted Einstein tensor. It is given in terms of the Bakry–Émery Ricci tensor as a tensor which is symmetric, divergence-free, concomitant of ...
