摘要
We present the low energy content of gauged Wess-Zumino-Witten models based on the coset SO(2, 2)/SO(2) x SO(1, 1). The background represent a cosmological theory of a universe that initially expands anisotropically and finally reaches a static limit. Using heterotic coset model techniques we include two sets of electromagnetic fields. (C) 1997 Published by Elsevier Science B.V.
