The g-Drazin inverses of anti-triangular block operator matrices
Huanyin Chen, Marjan Sheibani
An element in a Banach algebra has g-Drazin inverse if there exists such that and . In this paper…
Pseudo core invertibility in Banach *-algebras and its applications
Huanyin Chen, Marjan Sheibani
We present new additive results for the pseudo core inverse in a Banach algebra with involution. The necessary and sufficient conditions under which the sum of two pseudo core inve…
The Core Inverse in a Banach Algebra with Involution
Marjan Sheibani, Huanyin Chen
We present new additive results for the core inverse in a Banach algebra with involution. We obtain necessary and sufficient conditions under which the sum of two core invertible e…
Group inverse for anti-triangular block operator matrices
Huanyin Chen, Marjan Sheibani
We present the existence of the group inverse and its representation for the block operator matrix under the condition $FEF…
Group invertibility of the sum in rings and its applications
Huanyin Chen, Dayong Liu, Marjan Sheibani
We present new additive results for the group invertibility in a ring. Then we apply our results to block operator matrices over Banach spaces and derive the existence of group inv…
The g-Drazin invertibility in a Banach algebra
Huanyin Chen, Marjan Sheibani
We present necessary and sufficient conditions under which the anti-triangular matrix over a Banach algebra has g-Drazin inve…
