New duality transformation in two-dimensional non-linear sigma models
A new T-duality transformation is found in two-dimensional non-linear sigma models. This is a straightforward generalisation of Abelian and non-Abelian T-dualities. It is shown, in particular, that a given non-linear sigma model can possess more than one dual theory. Finally, the construction of this duality is given a geometrical interpretation. e-mail: [email protected] CNRS UMR ...
متن کاملT-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 کاملExact duality transformations for sigma models and gauge theories
We present an exact duality transformation in the framework of Statistical Mechanics for various lattice models with non-Abelian global or local symmetries. The transformation applies to sigma models with variables in a compact Lie group G with global G×G-symmetry (the chiral model) and with variables in coset spaces G/H and a global G-symmetry (for example, the non-linear O(N) or RPN models) i...
متن کاملFUZZY ORDERED SETS AND DUALITY FOR FINITE FUZZY DISTRIBUTIVE LATTICES
The starting point of this paper is given by Priestley’s papers, where a theory of representation of distributive lattices is presented. The purpose of this paper is to develop a representation theory of fuzzy distributive lattices in the finite case. In this way, some results of Priestley’s papers are extended. In the main theorem, we show that the category of finite fuzzy Priestley space...
متن کاملScattering and Duality in the 2 Dimensional Osp (2|2) Gross Neveu and Sigma Models
We write the thermodynamic Bethe ansatz for the massive OSp(2|2) Gross Neveu and sigma models. We find evidence that the GN S matrix proposed by Bassi and Leclair [12] is the correct one. We determine features of the sigma model S matrix, which seem highly unconventional; we conjecture in particular a relation between this sigma model and the complex sine-Gordon model at a particular value of t...
