英文摘要 | 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 if so is 1 + a‡b, and the related formulae are provided. |
