Noncommutative 6D Gauge Higgs Unification Models
J. C. Lopez-Dominguez, O. Obregon, C. Ramirez
The influence of higher dimensions in noncommutative field theories is considered. For this purpose, we analyze the bosonic sector of a recently proposed 6 dimensional SU(3) orbifo…
Non-Abelian Born-Infeld theory without the square root
O. Obregon
A non-Abelian Born-Infeld theory is presented. The square root structure that characterizes the Dirac-Born-Infeld (DBI) action does not appear. The procedure is based on an Abelian…
Noncommutative Topological Half-flat Gravity
H. Garcia-Compean, O. Obregon, C. Ramirez
We formulate a noncommutative description of topological half-flat gravity in four dimensions. BRST symmetry of this topological gravity is deformed through a twisting of the usual…
Towards the entropy of gravity time-dependent models via the Cardy-Verlinde formula
Octavio Obregon, Leonardo Patino, Hernando Quevedo
For models with several time-dependent components generalized entropies can be defined. This is shown for the Bianchi type IX model. We first derive the Cardy-Verlinde formula unde…
Noncommutative Self-dual Gravity
H. Garcia-Compean, O. Obregon, C. Ramirez +1
Starting from a self-dual formulation of gravity, we obtain a noncommutative theory of pure Einstein theory in four dimensions. In order to do that, we use Seiberg-Witten map. It i…
Noncommutative Topological Theories of Gravity
H. Garcia-Compean, O. Obregon, C. Ramirez +1
The possibility of noncommutative topological gravity arising in the same manner as Yang-Mills theory is explored. We use the Seiberg-Witten map to construct such a theory based on…
