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 ...
