The light-cone gauge formulation is quite advantageous for the construction of interactions. The generator p- is the Hamiltonian and we can simply ask if we can add interaction terms to it and still keep an algebra that closes. It turns out that all generators that transform the system out ...
We study different aspects of the construction of D = 4, N = 1 type IIB orientifolds based on toroidal ja:math . We find that tadpole cancellation conditions are in general more constraining than in six dimensions and that the standard Gimon-Polchinski orientifold projection leads to the impo...

Much of recent model building work has been in the strongly coupled regime of F-theory due to the presence of exceptional symmetries which allow for the construction of phenomenologically appealing Grand Unified Theories. We review both local and global F-theory model building starting from the ...

By imposing the spherical symmetry in the resulting five dimensional theory, we further reduce the s-wave sector of the theory to a two dimensional dilaton gravity. Via this construction, the techniques developed for the general two dimensional dilaton gravities are applicable in this context. ...
During recent years, a lot of efforts were focussed on the construction of N = 2 super- conformal (heterotic) string backgrounds [1]. These backgrounds lead to target space supersymmetry and, consequently, the perturbative vacuum is guar... TMGN = 被引量: 0发表: 0年 From the Berkovits fo...
We extend our previous construction of global solutions to Type IIB super-gravity that are invariant under the superalgebra F(4) and are realized on a spacetime of the form AdS6× S2 warped over a Riemann surface Σ by allowing the supergravity fields to have non-trivial SL(2, ℝ) mo...
