Quantization of the open string on plane-wave limits of dS_n x S^n and non-commutativity outside branes
G. Horcajada, F. Ruiz Ruiz
The open string on the plane-wave limit of with constant and dilaton background fields is canonically quantized. This entails solving the classical equation…
Noncommutative Einstein-Maxwell pp-waves
S. Marculescu, F. Ruiz Ruiz
The field equations coupling a Seiberg-Witten electromagnetic field to noncommutative gravity, as described by a formal power series in the noncommutativity parameters , is…
Position-dependent noncommutative products: classical construction and field theory
V. Gayral, J. M. Gracia-Bondia, F. Ruiz Ruiz
We look in Euclidean for associative star products realizing the commutation relation , where the noncommutativity parameters depend on the pos…
Trouble with space-like noncommutative field theory
V. Gayral, J. M. Gracia-Bondia, F. Ruiz Ruiz
It is argued that the one-loop effective action for a space-like noncommutative scalar field theory does not exist. This indicates that such theories are not renormalizable already…
Anomaly freedom in Seiberg-Witten noncommutative gauge theories
Friedemann Brandt, C. P. Martin, F. Ruiz Ruiz
We show that noncommutative gauge theories with arbitrary compact gauge group defined by means of the Seiberg-Witten map have the same one-loop anomalies as their commutative count…
Regularization and Renormalization of Chern-Simons Theory
G. Giavarini, C. P. Martin, F. Ruiz Ruiz
We analyze some features of the perturbative quantization of Chern-Simons theory (CST) in the Landau gauge. In this gauge the theory is known to be perturbatively finite. We consid…
