摘要
硕士学位论文《Banach空间上算子代数K-理论初探》是泛函分析学科Banach空间理论与算子理论有机结合进行初步探索的产物,在§1,通过引入(半)Browder算子等概念,说明这类算子在可交换的“小”摄动下的稳定性,深化了对算子Browder谱的认识;其后的章节,都是对国际研究新动向:把Banach空间结构理论中G-M系列成果引入算子代数K-理论密切关注、努力跟进取得的初步结果,其中,中心工作是§3:把最近Laustsen N.J.所求出的严格奇异算子理想S(X)的K-群的结果扩大到含于Riesz算子类中的各种算子理想(包括严格余奇异算子理想S~c(X),非本性算子理想J(X)等)都成立,在§4,则是在对某些G-M型Banach空间分类深化认识的基础上,直接应用§3的结果对某些类Banach空间X(如商遗传不可分解空间,不能合成空间等),求出其上有界线算子全体所构成的Banach代数的K-群K_0(B(X))和K_1(B(X)).
