We consider the dynamics of a contracting universe ruled by two minimally coupled scalar fields with general exponential potentials. This model describes string-inspired scenarios in the Einstein frame. Both background and perturbations can be solved analytically in this model. Curvature perturbations are generated with a scale invariant spectrum only for a dust-like collapse, as happens for a ...

The thermodynamic Bethe ansatz method is employed for the study of the integrable critical RSOS(q1, q2; q) model. The high and low temperature behavior are investigated, and the central charge of the effective conformal field theory is derived.
