- Abstract : Various characterizations of unbounded closed densely defined
operators commuting with the spectral measures of their moduli are
established. In particular, Kaufman’s definition of an unbounded quasinormal
operator is shown to coincide with that given by the third-named
author and Szafraniec. Examples demonstrating the sharpness of results
are constructed.
