Generalized and hypergeneralized projectors, introduced by Groß and Trenkler [Linear Algebra Appl. 264 (1997) 463], are revisited. Several properties of such matrices are established. Some of the results obtained extend and/or generalize those given in the reference above, and some others are soluti

Several results scattered in the literature express an oblique projector having given onto and along spaces in terms of a pair of orthogonal projectors. The results were established in various settings, including finite and infinite dimensional vector spaces over either real or complex numbers, but
