The Fuglede Putnam theorem for quasihyponormal operators
... In 1977, Stampli and Wadhwa [10] showed that if A ∗ ∈ Ꮾ ( Ᏼ ) is hyponormal, B ∈ Ꮾ() is dominant, C ∈ Ꮾ(Ᏼ,) is injective and has dense range, and if CA = BC, then A and B are normal. On the other hand, in 1981, Gupta ... See full document
