Rolling G2 moduli
Journal of High Energy Physics 8:1 (2004) 1169-1184
Abstract:
We study the time evolution of freely rolling moduli in the context of M-theory on a G2 manifold. This free evolution approximates the correct dynamics of the system at sufficiently large values of the moduli when effects from non-perturbative potentials and flux are negligible. Moduli fall into two classes, namely bulk moduli and blow-up moduli. We obtain a number of non-trivial solutions for the time-evolution of these moduli. As a generic feature, we find the blow-up moduli always expand asymptotically at early and late time. © SISSA/ISAS 2004.Gauge five-brane dynamics and small instanton transitions in heterotic models
