Keywords: Idempotent, Projector, Generalized projector, Hypergeneralized projector, Moore-Penrose inverse,


The aim of this paper is to give alternate representations of the Moore-Penrose inverse of a linear combination of generalized and hypergeneralized projectors and to provide alternate proofs of the invertibility of some linear combination of commuting generalized and  hypergeneralized projectors.
