String Dualities and the Geroch Group

Ioannis Bakas

We examine the properties and symmetries of the lowest order effective theory of 4-dim string backgrounds with axion and dilaton fields and zero cosmological constant. The dimensio…

Space Time Interpretation of S-Duality and Supersymmetry Violations of T-Duality

Ioannis Bakas

The S--duality transformations of the lowest order string effective theory admit a space time interpretation for 4-dim backgrounds with one Killing symmetry. Starting from pure gra…

O(2,2) Transformations and the String Geroch Group

I. Bakas

The 1--loop string background equations with axion and dilaton fields are shown to be integrable in four dimensions in the presence of two commuting Killing symmetries and …
