Nonlinear Waves and Solitons

We present a few remarks on disconnected components of the moduli space of heterotic string compactifications on T2. We show in particular how the eight dimensional CHL heterotic string can be understood in terms of topologically non-trivial E8×E8 and Spin(32)/Z2 vector bundles over the torus, and that the respective moduli spaces coincide.
