    Classical Solutions of Sigma Models in Curved Backgrounds by the Poisson-Lie T-Plurality

  • Original language description

    Classical equations of motion for three-dimensional ?-models in curved background are solved by a transformation that follows from the Poisson-Lie T-plurality and transform them into the equations in the flat background. Transformations of coordinates that make the metric constant are found and used for solving the flat model. The Poisson-Lie transformation is explicitly performed by solving the PDE's for auxiliary functions and finding the relevant transformation of coordinates in the Drinfel'd double. String conditions for the solutions are preserved by the Poisson-Lie transformations. Therefore we are able to specify the type of ?-model solutions that solve also equations of motion of three-dimensional relativistic strings in the curved backgrounds. Some simple examples are given.

    Klasická řešení Sigma modelů na zakřiveném pozadí pomocí Poisson-Lie T-plurality

  • Czech description

    Klasické pohybové rovnice třídimenzionálních Sigma modelů na zakřiveném pozadí jsou řešeny pomocí Poisson-Lie T-pluralitní transformace, která je převádí na rovnice v plochém prostoru. Poisson-Lie transformace zachovává strunové podmínky pro tato řešení,proto bylo možno určit řešení Sigma modelů, které řeší pohybové rovnice třídimensionálních relativistických strun v zakřiveném prostoru. Jednoduché příklady těchto řešení jsou dány.
