We consider the Fourier-Stieltjes algebra of a locally compact group G. We show that operator amenability of implies that a certain semitopological compactification of G admits only finitely many idempotents. In the case that G is connected, we show that operator amenability of entails that G is compact.

傅里叶-Stieltjes代数的算符适用性
我们考虑傅立叶-Stieltjes代数 局部紧致群G的一个。我们显示出暗示G的某种半拓扑紧缩只允许有限的许多幂等。在连接了G的情况下,我们表明意味着G是紧凑的。
