Brane World Cosmology with Gauss-Bonnet Interaction
B. Abdesselam, N. Mohammedi
We study a Randall-Sundrum model modified by a Gauss-Bonnet interaction term. We consider, in particular, a Friedmann-Robertson-Walker metric on the brane and analyse the resulting…

New duality transformation in two-dimensional non-linear sigma models
N. Mohammedi
A new T-duality transformation is found in two-dimensional non-linear sigma models. This is a straightforward generalisation of Abelian and non-Abelian T-dualities.

Poisson-Lie Duality in the String Effective Action
A. Bossard, N. Mohammedi
The symmetry properties of the bosonic string effective action under Poisson-Lie duality transformations are investigated. A convenient and simple formulation of these duality tran…
