Empirical Equivalence, Scientific Realism and String Theory
The phenomenon of duality in string theory provides an example of the underdetermination of the theoretical scheme by all possible empirical data. Empirically equivalent theories which arise due to string dualities differ in essential characteristics like the dimension and the topological position of their elementary objects and the form and dimensionality of spacetime. The obvious ontological ...
متن کاملUnification of String Dualities
We argue that all conjectured dualities involving various string, Mand F theory compactifications can be ‘derived’ from the conjectured duality between type I and SO(32) heterotic string theory, T-dualities, and the definition of Mand F theories. (Based on a talk given at the conference on ‘Advanced Quantum Field Theory’, Le Londe-les-Maures, France, Aug.31-Sept.5, 1996, in memory of Claude Itz...
متن کاملBrane Actions and String Dualities
An effective action for the M9-brane is proposed. We study its relation with other branes via dualities. Among these, we find actions for branes which are not suggested by the central charges of the Type II superalgebras. To be published in the proceedings of the TMR-meeting Quantum Aspects of Gauge Theories, Supersymmetry and Unification, Corfu, Greece, September 1998.
متن کاملString Dualities from Matrix Theory
We suggest that the (2,0) six dimensional field theory compactified on S × K3 is the Matrix model description of both M-theory on K3 and the Heterotic string on T . This proposal is different from existing proposals for the Heterotic theory. Different limits of the base space geometry give the different space-time interpretations, making Mtheory/Heterotic duality manifest. We also present parti...
متن کاملGauge–string Dualities and Some Applications
The first part of these lectures contains an introductory review of the AdS/CFT duality and of its tests. Applications to thermal gauge theory are also discussed briefly. The second part is devoted to a review of gauge-string dualities based on various warped conifold backgrounds, and to their cosmological applications.
