摘要：

We study supersymmetric compactifications of type Il strings on eightfolds to two dimensions. It is demonstrated that the type IIB string on an eightfold is free of gravitational anomalies. T-duality requires that this theory when further compactified on a circle must have a vacuum momentum; this is explicitly shown to be present and to have the right value. A subtlety in the relation of IIB compactifications and M-theory orientifolds to two dimensions is pointed out. (C) 1997 Published by Elsevier Science B.V.
