A comment on discrete Kalb-Ramond field on orientifold and rank reduction
I. Pesando
We show that the rank reduction of the gauge group on orientifolds in presence of non vanishing discrete Kalb-Ramond field can be explained by the presence of an induced field stre…
Boundary states for branes with non trivial homology in constant closed and open background
I. Pesando
For the bosonic string on the torus we compute boundary states describing branes with not trivial homology class in presence of constant closed and open background. It turns out th…
Some remarks on the free fields realization of the bosonic string on AdS3
Igor Pesando
We discuss the classical solutions of the equations of motion and the possible boundary condition for a bosonic string with Kalb-Ramond background in AdS3. It turns out that there…
A detailed case study of the rigid limit in Special Kähler geometry using K3
Marco Billo, Frederik Denef, Pietro Fre +4
This is a résumé of an extensive investigation of some examples in which one obtains the rigid limit of N=2 supergravity by means of an expansion around singular points in the modu…
