Abstract
The classes of k-rooted and ∞-rooted completely positive matrices are introduced. It is shown that completely positive matrices with at most two different eigenvalues are ∞-rooted, and completely positive singular ∞-rooted matrices of order 3 are characterized. Positive semidefinite matrices whose large powers are non-negative are also characterized.
