The T-dual symmetries of a bosonic string
Lj. Davidović, B. Sazdović
We investigate whether the symmetry transformations of a bosonic string are connected by T-duality. We start with a standard closed string theory. We continue with a modified open…
Open string T-duality in a weakly curved background
Ljubica Davidović
We consider a theory of an open string moving in a weakly curved background, composed of a constant metric and a linearly coordinate dependent Kalb-Ramond field with an infinitesim…
T-dualization in a curved background in absence of a global symmetry
Lj. Davidović, B. Sazdović
We investigate T-duality of a closed string moving in a weakly curved background of the second order. A previously discussed weakly curved background consisted of a flat metric and…
T-duality diagram for a weakly curved background
Ljubica Davidović, Bojan Nikolić, Branislav Sazdović
In one of our previous papers we generalized the Buscher T-dualization procedure. Here we will investigate the application of this procedure to the theory of a bosonic string movin…
Canonical approach to the closed string noncommutativity
Ljubica Davidovic, Bojan Nikolic, Branislav Sazdovic
We consider the closed string moving in the weakly curved background and its totally T-dualized background. Using T-duality transformation laws, we find the structure of the Poisso…
T-duality in the weakly curved background
Lj. Davidović, B. Sazdović
We consider the closed string propagating in the weakly curved background which consists of constant metric and Kalb-Ramond field with infinitesimally small coordinate dependent pa…
