On unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)
Abstract
It is a well-known result in op erator theory that whenever two op erators are similar then they have equal
sp ectra even though they do not have to belong to the same class of op erators. However ...
