Various results that relate to
almost similarity and other classes of
operators such as isometry, normal, unitary
and compact operators have been extensively
discussed. In this paper, we describe the
spectral picture of almost similar operators. To
be more specific we will describe the spectrum,
the spectral radius, the numerical radius as
well as the norm of almost similar operators.
