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…
Non-commutativity parameters depend not only on the effective coordinate but on its T-dual as well
Ljubica Davidović, Branislav Sazdović
We extend our investigations of the open string propagation in the weakly curved background to the case when Kalb-Ramond field, beside the infinitesimal term linear in coordinate $…
Noncommutativity in space-time extended by Liouville field
B. Nikolic, B. Sazdovic
The world-sheet quantum conformal invariance can be realized in the presence of the conformal factor , by inclusion of Liouville term. In the background with linear dilaton fiel…
Canonical approach to 2D supersymmetric WZNW model coupled to supergravity
O. Miskovic, B. Sazdovic
Starting from the known representation of the Kac-Moody algebra in terms of the coordinates and momenta, we extend it to the representation of the super Kac-Moody and super Virasor…
Canonical approach to 2D WZNW model, non-abelian bosonization and anomalies
B. Sazdovic
The gauged WZNW model has been derived as an effective action, whose Poisson bracket algebra of the constraints is isomorphic to the commutator algebra of operators in quantized fe…
W-Strings on Curved Backgrounds
A. Mikovic, B. Sazdovic
We discuss a canonical formalism method for constructing actions describing propagation of W-strings on curved backgrounds. The method is based on the construction of a representat…
W-Strings on Group Manifolds
A. Mikovicć, B. Sazdović
We present a procedure for constructing actions describing propagation of W-strings on group manifolds by using the Hamiltonian canonical formalism and representations of W-algebra…
