Duality symmetries in string theory
Abstract
The search for a unified theory of quantum gravity and gauge interactions leads naturally to string theory. This field of research has received a revival of interest after the discovery of duality symmetries in recent years. We present a self contained account of some nonperturbative aspects of string theory which have been recently understood. The spectrum and interactions of the five consistent superstring theories in ten dimensions are recollected and the fundamental principles underlying this initial stage in the construction of the theory are briefly reviewed. We next discuss some evidences that these apparently different superstrings are just different aspects of one unique theory. The key to this development is given by the nonperturbative duality symmetries which have modified and improved our understanding of string dynamics in many ways. In particular, by relating the fundamental objects of one theory to solitons of another theory, they have unraveled the presence of extended objects in the theory which stand on an equal footing with strings. We introduce these higher dimensional objects, named Dbranes, and discuss applications of Dbrane physics.

Duality symmetries in the partition functions of closed strings compactified on tori and orbifolds are shown to be a direct consequence of the quantumlevel fieldtheory duality of the associated twodimensional {sigma} models. This is demonstrated on both genus0 and genus1 world sheets.

Duality in quantum field theory (and string theory)
These lectures give an introduction to duality in Quantum Field Theory. We discuss the phases of gauge theories and the implications of the electricmagnetic duality transformation to describe the mechanism of confinement. We review the exact results of N=1 supersymmetric QCD and the SeibergWitten solution of N=2 super YangMills. Some of its extensions to String Theory are also briefly discussed. 
Origin of Abelian gauge symmetries in heterotic/Ftheory duality
Here, we study aspects of heterotic/Ftheory duality for compactifications with Abelian gauge symmetries. We consider Ftheory on general CalabiYau manifolds with a rank one MordellWeil group of rational sections. By rigorously performing the stable degeneration limit in a class of toric models, and also derive both the CalabiYau geometry and the spectral cover describing the vector bundle in the heterotic dual theory. We carefully investigate the spectral cover employing the group law on the elliptic curve in the heterotic theory. We find in explicit examples that there are three different classes of heterotic duals that have U(1) factors in theirmore »Cited by 6 
Discrete symmetries in Heterotic/Ftheory duality and mirror symmetry
We study aspects of Heterotic/Ftheory duality for compacti cations with Abelian discrete gauge symmetries. We consider Ftheory compacti cations on genusone bered CalabiYau manifolds with nsections, associated with the TateShafarevich group Z _{n}. Such models are obtained by studying rst a speci c toric setup whose associated Heterotic vector bundle has structure group Z _{n}. By employing a conjectured Heterotic/Ftheory mirror symmetry we construct dual geometries of these original toric models, where in the stable degeneration limit we obtain a discrete gauge symmetry of order two and three, for compacti cations to six dimensions. We provide explicit constructions of mirrorpairsmore »Cited by 1 
Dualitysymmetric string theory and the cosmologicalconstant problem
We propose an ansatz for a lowenergy effective action {ital {bar S}} for a gravityplusmatter system which is given by the usual action {ital S} (integral over spacetime) {ital divided} by the spacetime volume, {ital {bar S}}={ital S}/{ital V}. The resulting gravitational equation is independent of the value of the cosmological constant that is present in {ital S}. We suggest that {ital {bar S}} can be considered as an approximation for the effective action in the dualitysymmetric'' closedstring theory in which the string coordinates {ital x} and their duals'' {ital {tilde x}} are treated as independent.
