Abstract: In this paper, we show that if T is p-ω-hyponormal, the nonzero points of the approximate and joint approximate point spectrum of T are identical; Moreover, we obtain a pair of inequalities similar to p-ω-hyponormal operators.

Key words: Furuta inequality, L?wner-Heinz inequality, approximate point spectrum, p- w-hyponormal operators
