Can one tell Einstein's unimodular theory from Einstein's general relativity?
- E. Álvarez
- Physics
- 19 January 2005
The so called unimodular theory of gravitation is compared with general relativity in the quadratic (Fierz-Pauli) regime, using a quite broad framework, and it is argued that quantum effects allow in…

- 11 November 1992
The general problems of three-dimensional quantum gravity are recapitulated here, with emphasis on the mathematical problems of defining the measure of the path integral over all three-dimensional…
