Abstract
We give a survey of results concerning various classes of bounded linear operators in a Banach space defined by means of kernels and ranges. We show that many of these classes define a spectrum that satisfies the spectral mapping property.
Keywords
spectral mapping theorem, ascent, descent, semiregular operators, quasi-Fredholm operators
