This paper studies the (elementwise) nonnegativity of the Moore-Penrose inverse of the powers as well as the product of nonnegative matrices. A key role is played by several lemmas, some of which are known, relating the generalized inverse of a power to products involving powers and (possibly different) generalized inverses of powers.
