An operator A, on an infinite dimensional complex Hilbert space H into itself, is said to be algebraically p-hyponormal, 0 < p SC 1, if there exists a polynomial q such that q(A) is p-hyponormal. In this paper we show that Weyl's theorems hold in the class of all algebraically p-hyponormal operators.
