Gravitational domain walls and p-brane distributions
I. Bakas, K. Sfetsos
We review the main algebraic aspects that characterize and determine the domain wall solutions of maximal gauged supergravity in various spacetime dimensions by considering consist…
Solitons of axion-dilaton gravity
I. Bakas
We use soliton techniques of the two-dimensional reduced beta-function equations to obtain non-trivial string backgrounds from flat space. These solutions are characterized by two…
Universal aspects of string propagation on curved backgrounds
I. Bakas, K. Sfetsos
String propagation on D-dimensional curved backgrounds with Lorentzian signature is formulated as a geometrical problem of embedding surfaces. When the spatial part of the backgrou…
Toda fields of SO(3) hyper-Kahler metrics and free field realizations
I. Bakas, K. Sfetsos
The Eguchi-Hanson, Taub-NUT and Atiyah-Hitchin metrics are the only complete non-singular SO(3)-invariant hyper-Kahler metrics in four dimensions. The presence of a rotational SO(2…
Toda Fields of SO(3) Hyper-Kahler Metrics
I. Bakas, K. Sfetsos
We examine the Toda frame formulation of the SO(3)-invariant hyper-Kahler 4-metrics, namely Eguchi-Hanson, Taub-NUT and Atiyah-Hitchin. Our method exploits the presence of a rotati…
Supersymmetry and Dualities
E. Alvarez, L. Alvarez-Gaume, I. Bakas
Duality transformations with respect to rotational isometries relate supersymmetric with non-supersymmetric backgrounds in string theory. We find that non-local world-sheet effects…
