Let $$G=K < imes A$$ be the semi-direct product group of a compact group K acting on an abelian locally compact group A. We describe the $$C^*$$ -algebra $$C^*(G)$$ of G in terms of an algebra of operator fields defined over the spectrum of G, generalizing previous results obtained for some special classes of such groups.

半直积 $$K < imes A$$ 的 $$C^*$$-代数

令 $$G=K < imes A$$ 是紧致群 K 作用于阿贝尔局部紧致群 A 的半直积群。我们描述 $$C^*$$ -代数 $$C^*( G)$$ 在 G 的频谱上定义的算子域的代数方面,概括了先前为此类群的某些特殊类别获得的结果。
