Representations for the pseudo Drazin inverse of elements in a Banach algebra
In this paper, we investigate the pseudo Drazin invertibility of the sum and the product of elements in a Banach algebra {A}. Given pseudo Drazin invertible elements a and b such that a2b=aba and b2a=bab, it is shown that ab is pseudo Drazin invertible and a+b is pseudo Drazin invertible if and only...
