Non-Compact Calabi-Yau Spaces and Other Non-Trivial Backgrounds for 4-D Superstrings
E. Kiritsis, C. Kounnas, D. Lust
A large class of new 4-D superstring vacua with non-trivial/singular geometries, spacetime supersymmetry and other background fields (axion, dilaton) are found. Killing symmetries…
String Propagation in Gravitational Wave Backgrounds
E. Kiritsis, C. Kounnas
The Conformal Field Theory of the current algebra of the centrally extended 2-d Euclidean group is analyzed. Its representations can be written in terms of four free fields (withou…
The Dual Faces of String Theory
E. Kiritsis
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact WZW and coset models, such duality…
Duality Symmetries and Topology Change in String Theory
E. Kiritsis
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that for backgrounds generated from WZW and coset CFT models such duality symme…
Axial Vector Duality as a Gauge Symmetry and Topology Change in String Theory
A. Giveon, E. Kiritsis
Lines generated by marginal deformations of WZW models are considered. The Weyl symmetry at the WZW point implies the existence of a duality symmetry on such lines. The duality is…
Exact Duality Symmetries in CFT and String Theory
E. Kiritsis
There is substancial overlap with hepth-9211081. More results are presented for duality in the non-compact case. It is argued that duality persists as a symmetry also in that case.
