摘要：
Duality under inversion of the cosmological scale factor is discussed both for the classical motion of strings in cosmological backgrounds and for genus zero, low energy effective actions. The string-modified, Einstein-Friedmann equations are then shown to possess physically-inequivalent, duality-related solutions which generically describe the "decay" of an initial, perturbative, flat D = 10 superstring vacuum towards a more interesting strong-coupling state through an appealing pre-big-bang cosmological scenario.
