Abstract

Groß and Trenkler [Generalized and hypergeneralized projectors, Linear Algebra Appl. 264 (1997) 463–474] have introduced two generalizations of orthogonal projectors called generalized projectors and hypergeneralized projectors. In this note we characterize these generalizations by their spectral decompositions.
