摘要

在本文中，我们继续研究了在acd=dbd和dba=aca的假设下，在不同种类的乘积ac和bd的共同性质。这些性质包括环上的广义强Drazin可逆性和广义Hirano可逆性，Banach代数环境中Fredholm元素和B-Fredholm元素的抽象索引，Banach空间上有界线性算子核的可补性和值域。

Further results on common properties of the products ac and bd

In this paper, we continue to investigate common properties of the products ac and bd in various categories under the assumption acd=dbd and dba=aca. These properties include generalized strongly Drazin invertibility and generalized Hirano invertibility in rings, abstract index of Fredholm elements and B-Fredholm elements in the Banach algebra context, complementability of kernels and ranges for bounded linear operators on Banach spaces.
