New Reflections on Gravitational Duality

Hugo Garcia-Compean, Octavio Obregon, Cupatitzio Ramirez

In general terms duality consists of two descriptions of one physical system by using degrees of freedom of different nature. There are different kinds of dualities and they have b…

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…

Towards SDp-brane Quantization

H. Garcia-Compean, G. Garcia-Jimenez, O. Obregon +1

The quantum mechanical analysis of the canonical hamiltonian description of the effective action of a SDp-brane in bosonic ten dimensional Type II supergravity in a homogeneous bac…

Regular non-twisting S-branes

Octavio Obregon, Hernando Quevedo, Michael P. Ryan

We construct a family of time and angular dependent, regular S-brane solutions which corresponds to a simple analytical continuation of the Zipoy-Voorhees 4-dimensional vacuum spac…

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…
