Boosting Away Singularities from Conformal String Backgrounds
Generalizing our previous work, we show how O(d, d) transformations can be used to " boost away " in new dimensions the physical singularities that occur generically in cosmological and/or black-hole conformal string backgrounds. As an example, we show how a recent model by Nappi and Witten can be made singularity-free via O(3, 3) boosts involving a fifth dimension.

Generalizing our previous work, we show how O(d; d) transformations can be used to "boost away" in new dimensions the physical singularities that occur generically in cosmological and/or black-hole conformal string backgrounds. As an example, we show how a recent model by Nappi and Witten can be made singularity-free via O(3; 3) boosts involving a fth dimension.
متن کاملHomogeneous Conformal String Backgrounds
We present exact solutions characterised by Bianchi-type I, II, III, V, VI 0 , VI h four-dimensional metric, space-independent dilaton, and vanishing torsion background, for the low energy string eeective action with zero central charge deecit. We show that, in such a context, curvature singularities cannot be avoided, except for the trivial case of at spacetime and constant dilaton. We also pr...
متن کاملNaked singularities in four-dimensional string backgrounds.
It is shown that gauged nonlinear sigma models can be always deformed by terms proportional to the field strength of the gauge fields (nonminimal gauging). These deformations can be interpreted as perturbations, by marginal operators, of conformal coset models. When applied to the SL(2, R) × SU(2)/ (U(1)× U(1)) WZWN model, a large class of four-dimensional curved spacetime backgrounds are obtai...
متن کاملBuilding String Field Theory around Non-conformal Backgrounds
The main limitations of string field theory arise because its present formulation requires a background representing a classical solution, a background defined by a strictly conformally invariant theory. Here we sketch a construction for a gauge-invariant string field action around non-conformal backgrounds. The construction makes no reference to any conformal theory. Its two-dimensional field-...
