Spinning strings in AdS_5 x S^5 and integrable systems
G. Arutyunov, S. Frolov, J. Russo +1
We show that solitonic solutions of the classical string action on the AdS_5 x S^5 background that carry charges (spins) of the Cartan subalgebra of the global symmetry group can b…

Cosmological string models from Milne spaces and SL(2,Z) orbifold
J. G. Russo
The -dimensional Milne Universe with extra free directions is used to construct simple FRW cosmological string models in four dimensions, describing expansion in the presence…
