Gravity and Einstein-Proca-Weyl theories extended to a class of Scalar gravity theories
We extend the recently proved relation between certain models of Non-Riemannian gravitation and Einstein-Proca-Weyl theories to a class of Scalar gravity theories, this is used to present a Black-Hole Dilaton solution with non-Riemannian connection.

متن کاملHow Noncommutative Gauge Theories Couple to Gravity
We study coupling of noncommutative gauge theories on branes to closed string in the bulk. We derive an expression for the gauge theory operator dual to the bulk graviton, both in bosonic string theory and superstring theory. In either case, we find that the coupling is different from what was expected in the literature when the graviton is polarized in the noncommutative directions. In the cas...

Ju ly 20 0 8 je a n -f ra n co is P o d ev in on the very smallest scales—the voids in between the smallest known elementary particles—by quantum laws and possibly explain it in terms of some fundamental constituents. Superstring theory is often described as the leading candidate to fill this role, but it has not yet provided an answer to any of these pressing questions. Instead, following its ...
متن کاملAlternative Theories of Gravity
ACKNOWLEDGEMENTS This work would not have been possible without the help of a lot of people. I would like to thank my family and friends for their encouragement, my collaborators David Mota and Robert Scherrer for their hard work and my office mate Simon West for innumerable delightful lunches. Most of all I would like to thank my supervisor, John Barrow, for his constant support, his guidance ...
متن کاملQuantum theories of dilaton gravity.
Quantization of two-dimensional dilaton gravity coupled to conformal matter is investigated. Working in conformal gauge about a fixed background metric, the theory may be viewed as a sigma model whose target space is parameterized by the dilaton φ and conformal factor ρ. A precise connection is given between the constraint that the theory be independent of the background metric and conformal in...
