Study on Hirano Invertibility of Two New Types of Perturbed Operator Matrices

Haibo Gou, Huanyin Chen

We investigate the Hirano invertibility of block-operator matrices in Banach algebras, and obtain the Hirano inverse of matrix $[A C B D]$ under two t…

Hirano inverse of anti-triangular matrix over Banach Algebras

Haibo Gou, Huanyin Chen

In this paper we investigate Hirano invertibility of anti-triangular matrix over a Banach algebra. Let $a \in A^{H}, b \in A^{sD} .$ If $b^{D} a = 0, ba b^{π} = 0,$ we prove…
