N=2 String Geometry and the Heavenly Equations
Hugo Garcia-Compean
In this paper we survey some of the relations between Plebanski description of self-dual gravity through the heavenly equations and the physics (and mathematics) of N=2 Strings. In…
Gravitational Anomalies in Noncommutative Field Theory
Sendic Estrada-Jimenez, Hugo Garcia-Compean, Carlos Soto-Campos
Gravitational axial and chiral anomalies in a noncommutative space are examined through the explicit perturbative computation of one-loop diagrams in various dimensions. The analys…
A Reduced Model of Noncommutative S-brane Spectrum
H. Garcia-Compean, J. Gonzalez-Beltran
CFT construction of S-branes describing the rolling and bouncing tachyons is analyzed in the context of a -noncommutative deformation of minisuperspace. Half s-brane and s-brane…
On the Berezin Description of Kahler Quotients
Iliana Carrillo-Ibarra, Hugo Garcia-Compean
We survey geometric quantization of finite dimensional affine Kahler manifolds. Its corresponding prequantization and the Berezin's deformation quantization formulation, as propose…
Remarks on Noncommutative Solitons
Hugo Garcia-Compean, Jorge Moreno
In the first part of this work we consider an unstable non-BPS Dp-\bar{Dp}-brane pair in Type II superstring theory. Turning on a background NS-NS B-field (constant and nonzero alo…
Searching for S-duality in Gravitation
H. Garcia-Compean, O. Obregon, C. Ramirez
We overview some attempts to find S-duality analogues of non-supersymmetric Yang-Mills theory, in the context of gravity theories. The case of MacDowell-Mansouri gauge theory of gr…
