Local Anomaly Cancellation, M-Theory Orbifolds and Phase-Transitions

Abstract

In this paper we consider orbifold compactifications of M-theory on $S^1/{\mathbf{Z}}_2\times T^4/{\mathbf{Z}}_2$. We discuss solutions of the local anomaly matching conditions by twisted vector, tensor and hypermultiplets confined on the local orbifold six-planes. In addition we consider phase-transitions among different solutions which are mediated by M-theory fivebranes which touch the local orbifold planes and are converted there to gauge instantons.
