On Cosmological String Backgrounds with Toroidal Isometries
Amit Giveon, Andrea Pasquinucci
A large class of cosmological solutions (of the Einstein equations) in string theory, in the presence of Maxwell fields, is obtained by transformations of simple backgroun…

On String Field Theory and Effective Actions
Amit Giveon
A truncation of string field theory is compared with the duality invariant effective action of heterotic strings to cubic order. The three string vertex must satisfy a s…

Gauge Symmetries of the N=2 String
Amit Giveon, Alfred Shapere
We study the underlying gauge symmetry algebra of the string, which is broken down to a subalgebra in any spacetime background. For given toroidal backgrounds, the unbroken g…
