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…
Time and "angular" dependent backgrounds from stationary axisymmetric solutions
Octavio Obregon, Hernando Quevedo, Michael P. Ryan
Backgrounds depending on time and on "angular" variable, namely polarized and unpolarized Gowdy models, are generated as the sector inside the horizons of the mani…
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…
