Generalized Unimodular Gravity in Friedmann and Kantowski—Sachs Universes
Abstract
We illustrate the recently proposed generalized unimodular gravity using simple examples of the Friedmann, Kantowski-Sachs and Schwarzschild geometries and show that it can be further generalized and reveal some unexpected and interesting effects.
