Open strings in Lie groups and associative products
Pierre Bieliavsky, Charles Jego, Jan Troost
Firstly, we generalize a semi-classical limit of open strings on D-branes in group manifolds. The limit gives rise to rigid open strings, whose dynamics can efficiently be describe…
D-branes in non-critical superstrings and duality in N=1 gauge theories with flavor
Sameer Murthy, Jan Troost
We study D-branes in the superstring background R^{3,1} \times SL(2,R)_{k=1}/U(1) which are extended in the cigar direction. Some of these branes are new. The branes realize flavor…
Superstring theories
Constantin Bachas, Jan Troost
We briefly review superstring theories, highlighting the important concepts, developments, and open problems of the subject.
The Topological Cigar Observables
Sujay K. Ashok, Jan Troost
We study the topologically twisted cigar, namely the SL(2,R)/U(1) superconformal field theory at arbitrary level, and find the BRST cohomology of the topologically twisted N=2 theo…
Notes on the Verlinde formula in non-rational conformal field theories
Charles Jego, Jan Troost
We review and extend evidence for the validity of a generalized Verlinde formula in particular non-rational conformal field theories. We identify a subset of representations of the…
