摘要：
An operator T is called (p, k)-quasihyponormal if T*(k)(\T\(2p) - \T*\(2p))Tk greater than or equal to 0, (0 < p less than or equal to 1; k is an element of Z(+)), which is a common generalization of p-quasihyponormality and k-quasihyponormality. In this paper we consider the Putnam's inequality, the Berger-Shaw's inequality, the Weyl's theorem and the tensor product for (p, k)-quasihyponormal operators.
