Janas, J. On unbounded hyponormal operators. III. (English) Zbl 0820.47025 Stud. Math. 112, No. 1, 75-82 (1994). Summary: The paper deals mostly with spectral properties of unbounded hyponormal operators. Some nontrivial examples of such operators are given.[For part II see Integral Equations Oper. Theory 15, 470-478 (1992; Zbl 0772.47005)].
