Abstract
ABSTRACT Let be a complex Banach algebra. An element has g-Drazin inverse if there exists such that New additive results for the g-Drazin inverse in a Banach algebra are presented. These extend the main results of Deng and Wei (J. Math. Analysis Appl., 379(2010), 313–321) and Wang et al. (Filomat, 30(2016), 1185–1193).
