我们证明了杂化超对称性（Killing旋量方程）和反常相消意味着五、六、七、八维中的杂化运动方程当且仅当切丛上的连接是瞬子。对于六维的杂合紧化，这减少了对具有零度稳定切丛的流形上唯一SU（3）瞬子的连接的选择。
We show that the heterotic supersymmetry (Killing spinor equations) and the anomaly cancellation imply the heterotic equations of motion in dimensions five, six, seven, eight if and only if the connection on the tangent bundle is an instanton. For heterotic compactifications in dimension six this reduces the choice of that connection to the unique SU(3) instanton on a manifold with stable tangent bundle of degree zero.
