摘要：

The restrictions imposed by anomaly cancellation on the chiral fermion content of nonsupersymmetric gauge theories based on various groups are studied in spacetime dimension D = 6, 8, and 10. In particular, we show that the only mathematically consistent chiral SU(5) theory in D = 6 contains three nonidentical generations.
