On pairs of generalized and hypergeneralized projections on a Hilbert space
2012 (English)Report (Other academic)
In this paper, we characterize generalized and hypergeneralized projections (bounded linear operators which satisfy conditions A2=A*and A2=A†). We give theirs matrix representations and examine under what conditions the products, differences, and sums of these operators are operators of the same class.
