Quantum Gravity and String Theory

    

The Exclusive Higher Dimensional Reductions of Heterotic and IIB Supergravity Theories

Authors: Boris Stoyanov

Superstring theory is the most promising candidate for unified quantum theory of the fundamental interactions including gravity. The purpose of this investigation is to study toroidal compactification of the type IIB theory and implications of SL(2, R) symmetry for the reduced action. It has been shown recently that the toroidally compactified type IIB string effective action possesses an SL(2, R) invariance as a consequence of the corresponding symmetry in ten dimensions when the self-dual five-form field strength is set to zero. We will study the toroidal compactification of type IIB string theory and explore some of the consequences of SL(2, R) invariance of ten dimensional theory. The compactified theory on a d-dimensional torus respects the symmetry when specify the transformation properties of the resulting scalar and vector fields.
