A Two-loop Test of Buscher’s T-duality I
نویسندگان
چکیده
We study the two loop quantum equivalence of sigma models related by Buscher’s T-duality transformation. The computation of the two loop perturbative free energy density is performed in the case of a certain deformation of the SU(2) principal sigma model, and its T-dual, using dimensional regularization and the geometric sigma model perturbation theory. We obtain agreement between the free energy density expressions of the two models.

T-Duality in Sigma-Models with Kaluza-Klein Metric as Electric-Magnetic Duality
It is shown that the T-duality in σ-model with Kaluza-Klein metric, without or with a torsion term, can be interpreted as electric-magnetic duality for some of their solitonic solutions. Actually Buscher’s duality transformation interchanges the topological and Noether charges. ∗E-mail: tabriz [email protected]
متن کاملAn Introduction to T-Duality in String Theory
In these lectures a general introduction to T-duality is given. In the abelian case the approaches of Buscher, and Roc̆ek and Verlinde are reviewed. Buscher’s prescription for the dilaton transformation is recovered from a careful definition of the gauge integration measure. It is also shown how duality can be understood as a quite simple canonical transformation. Some aspects of non-abelian dua...
متن کاملA Canonical Approach to Duality Transformations
We show that Buscher’s abelian duality transformation rules can be recovered in a very simple way by performing a canonical transformation first suggested by Giveon, Rabinovici and Veneziano. We explore the properties of this transformation, and also discuss some aspects of non-abelian duality.

متن کاملT-Duality and Space-Time Supersymmetry
We analyze in detail the possible breaking of space-time supersymmetry under Tduality transformations. We find that when appropiate world-sheet effects are taken into account apparent puzzles concerning supersymmetry in space-time are solved. We study T-duality in general heterotic σ-models analyzing possible anomalies, and we find some modifications of Buscher’s rules. We then work out a simpl...
متن کاملExponential membership function and duality gaps for I-fuzzy linear programming problems
Fuzziness is ever presented in real life decision making problems. In this paper, we adapt the pessimistic approach tostudy a pair of linear primal-dual problem under intuitionistic fuzzy (I-fuzzy) environment and prove certain dualityresults. We generate the duality results using exponential membership and non-membership functions to represent thedecision maker’s satisfaction and dissatisfacti...
