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.
