Enrico Boasso, Dragan S. Djordjević, Dijana Mosić · Journal of the Korean Mathematical Society · 2013
The weighted Moore-Penrose inverse will be introduced and studied in the context of Banach algebras. In addition, weighted EP Banach algebra elements will be characterized. The Banach space operator case will be also considered.
