Abstract: Abstract. Let T be a bounded linear operator on a complex Hilbert space H. T is called (p, k)-quasihyponormal if T*((T*T)p− (TT*)p)T ≥ 0 for 0 < p ≤ 1 and k € N. In this paper, we prove that Weyl type theorems for (p, k)-hyponormal operators. Especially we prove that if T is (p, k)-quasihyponormal, then generalized a-Weyl’s theorem holds for T.
