Abstract
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.
