Abstract
We show that the N=1 supergravity theories in ten dimensions with gauge groups U(1){496} and E{8}×U(1){248} are not consistent quantum theories. Cancellation of anomalies cannot be made compatible with supersymmetry and Abelian gauge invariance. Thus, in ten dimensions all supersymmetric theories of gravity without known inconsistencies are realized in string theory.
摘要
我们表明，具有规范群 U(1){496}和 E{8}×U(1){248}的十维 N=1 超引力理论不是一致的量子理论。反常的消除不能与超对称性和阿贝尔规范不变性兼容。因此，在十维空间中，所有没有已知不一致性的超对称引力理论都在弦论中得到实现。
