Berezin Quantization of Gauged WZW and Coset Models
I. Carrillo-Ibarra, H. Garcia-Compean, W. Herrera-Suarez
Gauged WZW and coset models are known to be useful to prove holomorphic factorization of the partition function of WZW and coset models. In this note we show that these gauged mode…
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…
A Noncommutative Deformation of Topological Field Theory
Hugo Garcia-Compean, Pablo Paniagua
Cohomological Yang-Mills theory is formulated on a noncommutative differentiable four manifold through the -deformation of its corresponding BRST algebra. The resulting noncommu…
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…
