摘要：
Generalized and hypergeneralized projectors, introduced by GroB 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 solutions to new problems. (C) 2004 Elsevier Inc. All rights reserved.
