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…

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…
