Orientifolds of the 3-sphere
Constantin Bachas, Nicolas Couchoud, Paul Windey
We study the geometry of orientifolds in the SU(2) WZW model. They correspond to the two inequivalent, orientation-reversing involutions of , whose fixed-point sets are: the n…

D-branes in some near-horizon geometries
C. Bachas
I review some properties of D-branes in the SU(2) and SL(2,R) WZW models. I comment on a potential difficulty for the realization of `warped brane worlds' in string theory. This sh…
