DUALITY IN STRING THEORY

International Journal of Geometric Methods in Modern Physics, 2013
Duality symmetries have played a key role in the discovery that the five consistent superstring theories in 10 dimensions emerge as different corners of the moduli space of a single unifying theory, known as M-theory. Focusing on the target space, or T, duality symmetry, we show how it can be formulated in spacetimes with abelian and non-abelian ...

Duality, strings and inflation

General Relativity and Gravitation, 1991
Arguments based on thermodynamics and on the analysis of string creation effects in expanding spaces suggest the existence of an inflationary phase in the early universe for theories of closed strings. Einstein's equations on the other hand do not support such expectations.

Dualities in String Cosmology

2007
We describe in this chapter a set of duality symmetries present in the string-inspired theory of gravity coupled to the dilaton. These dualities are the cornerstones of String Cosmology, which provides alternatives to the usual inflation scenario. The crucial role of Prof.
