Query: Anomaly Analysis of Brane-Antibrane Systems   String theories with branes can often be generalized by adding
brane-antibrane pairs. We explore the cancellation of anomalies in this more
general context, extending the familiar anomaly-cancelling mechanisms, both for
ten-dimensional string theories with D-branes and for certain supersymmetric
compactifications.
