Poisson-Lie transformations and Generalized Supergravity Equations
Ladislav Hlavatý, Ivo Petr
In this paper we investigate Poisson-Lie transformation of dilaton and vector field J appearing in Generalized Supergravity Equations. While the formulas appearing in literature wo…
T-folds as Poisson-Lie plurals
Ladislav Hlavatý, Ivo Petr
In previous papers we have presented many purely bosonic solutions of Generalized Supergravity Equations obtained by Poisson-Lie T-duality and plurality of flat and Bianchi cosmolo…
Poisson-Lie plurals of Bianchi cosmologies and Generalized Supergravity Equations
Ladislav Hlavatý, Ivo Petr
Poisson-Lie T-duality and plurality are important solution generating techniques in string theory and (generalized) supergravity. Since duality/plurality does not preserve conforma…
Poisson-Lie identities and dualities of Bianchi cosmologies
Ladislav Hlavatý, Ivo Petr
We investigate a special class of Poisson--Lie T-plurality transformations of Bianchi cosmologies invariant with respect to non-semisimple Bianchi groups. For six-dimensional semi-…
Poisson-Lie T-plurality revisited. Is T-duality unique?
Ladislav Hlavaty, Ivo Petr
We investigate (non-)Abelian T-duality from the perspective of Poisson-Lie T-plurality. We show that sigma models related by duality/plurality are given not only by Manin triples o…
Plane-parallel waves as duals of the flat background III: T-duality with torsionless -field
Ladislav Hlavaty, Ivo Petr, Filip Petrasek
By addition of non-zero, but torsionless -field, we expand the classification of (non-)Abelian T-duals of the flat background in four dimensions with respect to one-, two-, thre…
Plane-parallel waves as duals of the flat background II: T-duality with spectators
Filip Petrasek, Ladislav Hlavaty, Ivo Petr
We give the classification of T-duals of the flat background in four dimensions with respect to one-, two-, and three-dimensional subgroups of the Poincaré group using non-Abelian…
Plane-parallel waves as duals of the flat background
Ladislav Hlavaty, Ivo Petr
We give a classification of non-Abelian T-duals of the flat metric in D=4 dimensions with respect to the four-dimensional continuous subgroups of the Poincare group. After dualizin…
New solvable sigma models in plane--parallel wave background
Ladislav Hlavaty, Ivo Petr
We explicitly solve the classical equations of motion for strings in backgrounds obtained as non-abelian T-duals of a homogeneous isotropic plane-parallel wave. To construct the du…
