Book 2011istensen,these timeless lecture notes, containing material or expositions not found in any other textbooks,are a gem to be discovered or re-discovered by anyone seriously interested in the study of gravitational physics.

Because ordinary derivatives become covariant derivatives when a gravitational field is present, this means that in general relativity matter field derivatives occur only in the combination

Once having found the energy–momentum–stress density for a conservative medium, we shall find it not difficult to introduce dissipative mechanisms either again phenomenologically or, if that is insufficien
