摘要
本文研究了算子代数的K-理论.利用代数拓扑方法,获得了复Hilbert空间上正常算子所生成算子代数的K-群与该算子谱几何性质的定性关系.
The article discuss the K-theory of operator algebras. By means of algebraic topology, we obtain a further relationship between the K-groups of the operator algebra of a normal operator in a complex Hilbert space and its spectral set, which has some nice geometric property.
