Abstract: The paper mainly uses the decomposition of the ΣKL of the matrix to give several new characteristics of generalized projectors(A2=A*)and hypergeneralized projectors(A2=A), which generalized some related results of Baksalary.

Key words: the mooer-penrose inverse, generalized projectors, group inverse, hypergeneralized projectors
