Normal ordering and boundary conditions for fermionic string coordinates
Nelson R. F. Braga, Hector L. Carrion, Cresus F. L. Godinho
We build up normal ordered products for fermionic open string coordinates consistent with boundary conditions. The results are obtained considering the presence of antisymmetric te…
Normal ordering and boundary conditions in open bosonic strings
Nelson R. F. Braga, Hector L. Carrion, Cresus F. L. Godinho
Boundary conditions play a non trivial role in string theory. For instance the rich structure of D-branes is generated by choosing appropriate combinations of Dirichlet and Neumann…
The Noncommutative U(N) Kalb-Ramond Theory
R. Amorim, C. N. Ferreira, C. F. L. Godinho
We present the noncommutative extention of the U(N) Cremmer-Scherk-Kalb-Ramond theory, displaying its differential form and gauge structures. The Seiberg-Witten map of the model is…
Fadeev Jackiw Analysis of Constraints on Noncomutative Hall Effect
C. F. L. Godinho
Constrained systems are fundamental to understanding of several physical realities. Even so the Hall effect is one of more revisited issue we can still find new approaches to obtai…
Fermionic anticommutators for open superstrings in the presence of antisymmetric tensor field
Nelson R. F. Braga, Cresus F. L. Godinho
We build up the anticommutator algebra for the fermionic coordinates of open superstrings attached to branes with antisymmetric tensor fields. We use both Dirac quantization and th…
